However, lasers only work when the unit has sufficient power. This was formally stated as follows: "The metric units for linear measurement in building and construction will meetric the metre m and the millimetre mmwith the kilometre km being used digital metric tape measure size required. By understanding how each of them works, you can determine which is best suited to your specific needs. You May Also Like. Useful for those who prefer to titrate in technology, these continue to be popular. Power Finally, you digital metric tape measure size to be able to run the measuring tape. This type of tape measure will have a floating tang or hook on the end to aid measuring.

Bang's rule was the first attempt in the United States to make a spring return pocket tape measure. The tape could be stopped at any point and held by the mechanism. The tape could be returned to the case by sliding a button on the side of the case which then allowed the spring to pull the tape back into the case. On 3 January , Hiram A. Farrand received patent 1,, for his concave-convex tape, a major improvement for spring pocket tape measures.

It was Farrand's concave-convex tape that went on to become the standard for the majority of pocket tape measure tapes today. The first patented for a long tape measure in the United States was patent 29, issued July 10, to William H.

Paine of Sheboygan, Wisconsin, [6] and produced by George M. Eddy and Company of Brooklyn, New York. This tape had no increments on it. It accurately measured only a distance equal to the total length of the tape from beginning to end marker, a brass piece attached to the tape at a measured distance. The measured length was marked on the case or crank. Later, by the early s, Justus Roe of Patchogue, New York added rivets attaching small brass washers to the tape to mark inches and feet.

They were attached every inch in the first and last foot and every foot from one to the end of the last foot. A small brass tag, marked with a number indicating the number of feet to that point, was attached every five feet.

This feature was never patented, but Justus Roe and Sons produced tape measures, "Roe Electric Reel Tape Measures", with this feature during the s and early s when they started etching or stamping increments and numbers on the tapes. The "electric" part of the name was purely an affectation; there was nothing electrical about it.

The basic design on which all modern spring tape measures are built can trace its origins back to an patent by a West Meriden, Connecticut resident named William H. Bangs Jr. According to the text of his patent, Bang's tape measure was an improvement on other versions previously designed. The spring tape measure has existed in the U. In the late s, carpenters began slowly adopting H. Farrand's design as the one more commonly used.

This design is the basis for most modern pocket tape measures used today. With the mass production of the integrated circuit IC the tape measure has also entered into the digital age with the digital tape measure.

Some incorporate a digital screen to give measurement readouts in multiple formats. An early patent for this type of measure was published in There are also other styles of tape measures that have incorporated lasers and ultrasonic technology to measure the distance of an object with fairly reliable accuracy. Tape measures often have black and red measurements on a yellow background as this is the optimal color combination for readability. Justus Roe, a surveyor and tape-maker by trade, made the longest tape measure in , at feet m.

The Northern Virginia Surveyors Association presented the foot, gold-plated surveyor's tape measure to Mickey Mantle in Some tapes sold in the United States have additional marks in the shape of small black diamonds, which appear every These are used to mark out equal spacing for joists five joists or trusses per US standard 8-foot 2, mm length of building material. Many US tapes also have special markings every 16 inches mm , which is a US standard interval for studs in construction.

Three spaces of 16 inches make exactly 4 feet 1, mm which is the US commercial width of a sheet of plywood , gyprock or particle board. For example, in some Walmarts there are Hyper Tough brand tapes available in both US customary units and Metric units. So, the inclusion of a metric scale requires the measuring device either to contain 3 scales of measurement or the elimination of one of the US Customary scales.

The use of millimeter only tape measures for housing construction is a part of the US metric building code. Millimeters produce whole integer numbers, reduce arithmetic errors, thus decreasing wastage due to such errors.

The US made measuring tape shown on the right is interesting in that it is a "Reverse Measuring Tape", where the measurements can be read from right to left just as well as they can be read when the tape is used from left to right. The metric roll-up tape shown is a millimeter only tape measure.

The building industry was the first major industry grouping in Australia to complete its change to metric , being completed by January In this the industry was grateful to the SAA now Standards Australia for the early production of the Standard AS "Metric Units for Use in the Construction Industry", which specified the use of millimetres as the small unit for the metrication upgrade. In the adoption of the millimetre as the "small" unit of length for metrication instead of the centimetre the Metric Conversion Board leaned heavily on experience in the UK and within Certified Digital Tape Measure Size the ISO , where this decision had already been taken.

This was formally stated as follows: "The metric units for linear measurement in building and construction will be the metre m and the millimetre mm , with the kilometre km being used where required. This will apply to all sectors of the industry, and the centimetre cm shall not be used.

The logic of using the millimetre in this context was that the metric system had been so designed that there would exist a multiple or submultiple for every use. Decimal fractions would not have to be used. Since the tolerances on building components and building practice would rarely be less than one millimetre, the millimetre became the sub-unit most appropriate to this industry. While dual scale tapes showing both inches and centimetres are sold, these are mainly imported low-cost items since it would be a restriction of trade to not allow their importation.

Tape measures sold in the UK often have dual scales for metric and imperial units. Like the American tape measures described above, they also have markings every 16 in Tape measures sold in Canada often have dual scales for metric and imperial units. All tapes in imperial units have markings every 16 in Home construction in canada is largely, if not entirely, in imperial measure. Tapes are used in surveying for measuring Horizontal, vertical or slope distances. Tapes are issued in various lengths and widths and graduated in variety of ways.

The accuracy of a tape measure is dependent on the ends of the tape and the markings printed onto the tape. The accuracy for the end of a retractable tape measure is dependent on the hook's sliding mechanism and thickness. The European Commission EC has standardised a non-compulsory classification system for certifying tape measure accuracy, with certified tapes falling into one of three classes of accuracy: Classes I, II, and III.

If a tape measure has been certified then the class rating is printed onto the tape alongside other symbols including the nominal length of the tape, the year of manufacture, the country of manufacture, and the name of the manufacturer.

Sending the messages to a crisp LCD display, you can quickly and easily get a readout. The controls are located at the sides, easy to use thanks to the simple design. While the default is metric, it takes only a push of a button to switch it over to imperial.

By operating on a rechargeable battery, it lends an economical edge that takes away the need for replacement batteries. Bear in mind that, though the USB charging is handy, it takes a bit of extra time between uses. Check the charge indicated on the screen before you get to work to prevent any nuisances. When the top priority is getting an exact reading, the Mileseey Digital Tape Measure is a worthy selection. It incorporates a large, bright LCD screen that takes any guesswork out of measuring things in the dark.

Reaching to feet away, it is easy to tackle large projects. For the times where you need to run calculations, this measuring tool is right there with you. From hypothesis to the hypotenuse, you can quickly glean anything from volume to angle. Swapping from metric to imperial in a jiffy, the precision capability and standard power source coupled with an automatic shutoff make this a well-suited workplace tool.

While this tape has comprehensive features, it can be a bit bulky to store especially since the screen can scratch. To avoid these pitfalls, keep it away from sharp objects and ready for the next task. The first thing to consider is your desired balance of analog Craftsman Digital Tape Measure Size and digital.

Some tape measures have both a physical tape and a laser, whereas others focus entirely on the laser aspect. Decide if you need both and go from there. Next, you want to determine the level of accuracy you will need. Be sure of the precision as you move forward. For instance, do you have to measure volume?

Sure, you can use paper and a pencil, but more advanced digital tape measures can do the work in a jiffy. Of course, you also want something that comes from a reputable brand that has a proven track record of success.

So long as you identify your priorities and focus on options that adhere to those values, you can find an ideal option. A digital tape measure is a tool used to accurately determine distance. Instead of using physical tape exclusively and requiring the user to eyeball the measurement, it relies on technology. By including sensors, either magnetic or light-operated, the measuring tape registers the distance and displays it on the screen. In standard functions width, length, etc.

However, digital options have more advanced features as well. They can convert between measurements. Even the most basic options include the ability to shift from inches to feet, to metric.

Battery operated, digital tape measures are powerful tools that enable a level of accuracy that the human eye simply cannot achieve alone. There are many advantages to using a digital tape measure, ranging from ease to efficiency.

The top virtue is range since lasers can shoot out far further than a physical tape can achieve. This lets you measure larger areas without having to compound physical measurements. Another key benefit is the precision offered by technology. Offering measurement capabilities beyond the linear, digital tape measures usually includes a memory feature that lets it store your previous settings and details. This means you can switch between imperial and metric without worry. Plus, more advanced measuring tools are able to go far beyond this.

By using straightforward formulas like those to calculate angles, hypotenuse length, and volume, you can save a lot of time and effort. There are several different types of digital tape measures , each with their own virtues. By understanding how each of them works, you can determine which is best suited to your specific needs.

While all tape measures are capable of reading distance in a linear fashion, there are advanced selections that take utility far beyond this point.

Ultimately, it is a matter of figuring out the sort of task you plan to use the tape measure for. So long as you identify the type of digital tape measure gears towards those needs, you can more easily complete the task.

This type of tape measure focuses entirely on the abilities of the laser and includes no analog tape function. The light beam operates as the tape instead. This offers a wider range than can be achieved with a standard tape since most laser parts can go as far as feet. Included with this type is either a replaceable or a rechargeable battery. This sort of digital tape measure is far more likely than others to have rechargeable capabilities.

Additionally, there is usually a larger screen and more functions. Typically, this type of digital tape measure can perform advanced calculations like volume and area.

With these digital tape measures, there is both a physical tape and a laser. While sometimes the laser has less of a range than exclusively digital options, it gives the benefit of having an analog backup. This way, if batteries die during a project, you can keep working. Though this type tends to be a bit smaller and somewhat heavier, there is still a digital display. It may be more petite, though it offers accurate readings to within the same standard deviation as other options.

You can find hybrid selections in various sizes, though more often than not they are powered by a set of replaceable batteries. The unit will likely be able to convert your units and store values in its memory. Sometimes, you can find a hybrid selection able to calculate advanced formulas. Useful for those who prefer to titrate in technology, these continue to be popular. A handy option for those with overflowing tool kits, this type of digital tape measure takes up less space than other options.

You can find compact digital tape measures in both exclusively digital and hybrid styles. Often, the unit will include a carrying pouch to protect it against damage. Powered by batteries and with a very small LCD display, this type of measuring tape usually features a long battery life. Typically, it will have an automatic shutoff with activity.

Given the size of the screen, it also extends battery life. The first is the type of tape. Choose something that works for you. The next thing to look for is range and precision. Opt for at least feet of range with the laser to give yourself the chance to measure larger areas. When assessing these digital tape measures , there are a few things we kept in mind. Broken into a couple of categories, we looked primarily at function, structure, and power.

By assessing each of these parameters as noted by the description, we were able to identify the top selections. First, we looked at function; finding the selections with the most ability digit conversion, accuracy, range, memory. The next step in our analysis, provided the tape met the standards for function, is looking at the structure.

Is the screen properly sized? Are the buttons accessible? Is it easy to read? Provided these lined up, we moved forward to the power section.

All digital tech requires a power source. So long as the power was accessible strong USB port or replaceable batteries , it made the cut. From there, we looked at the products repute and track record before making our final recommendations. As with any tool, there are some essential features to make your experience a successful one. Sure, some are more critical than others; but, when you find a tape measure that has all these features and more, you can rely on it to work.

Prioritize the features and, from there, you can identify the best digital tape measure for you. What sets digital tape measures apart from their analog counterparts is the LCD display.

This feature lets you interpret the results achieved by the digital component. Sometimes the screens are a few square inches and sometimes they are quite small. Within this component, you can find a lot of other features, too. For instance, larger screens can display more simultaneously.

They also enable you to see more clearly, especially when the screen is backlit. This is where to keep an eye on resolution and waterproof abilities especially if you work in humid areas. So long as the screen is well-placed and large enough, you can achieve the desired results. While tape may be a loose term, the reach of the measuring tape counts for a lot.

Sure, some options have both a physical tape and a light beam. However, even if the tape is just a laser pointer, it can work equally as well, if not more precisely. The idea is to identify the quality of the tape and how it relates to the measurement sensors. With lasers, you can expect a range of roughly feet while a tape will have drastically less reach.

However, lasers only work when the unit has sufficient power. So long as the laser interfaces well with the display, it is a good way to go. Naturally, your tape measure needs to perform the key job: measuring. However, not all readings are made alike.

For one, you need to keep an eye on the accuracy. So long as this can be achieved, you are getting the full benefits of the digital features since human readings at this accuracy level are subject to flaw. You also want measurements that work in multiple metrics. Ideally, it will be able to complete formulas, saving you time.

You can find selections that measure volume and readings according to the Pythagorean theorem right angle triangles. Finally, you need to be able to run the measuring tape. There are two options within this category, both viable and more a matter of personal convenience.

The first is replaceable batteries which are the most common designs on the market. The other option is a rechargeable battery that uses a USB cord to recharge the internal system.

Provided you have access to a laptop, a PC, or a wall adapter like those found with cell phones, this is a viable option. However, when you take it on the road, you may want something with a replaceable battery backup. Just like with any tool, digital tape measures have specific maintenance requirements.

While this is fairly straightforward, prudent scheduling of preventative upkeep can drastically improve the shelf life of your measurement tool. As with most things, it comes down to both storage and cleaning. The idea is to keep it in prime condition for when you need it.
