We used the 95% confidence interval of the ICC (95%CI) as the basis for evaluating the level of reliability using the following general guideline. Values less than 0.5 are indicative of poor reliability, values between 0.5 and 0.75 indicate moderate reliability, values between 0.75 and 0.9 indicate good reliability, and values greater than 0.90 indicate excellent reliability [ 3]. Always wanted to know how to take that particularly awkward measurement or how to take care of your tool? Perhaps you're interested in how particular trades use their tools? Then read on... Got a tip to share? Then get in touch! How to Read a Tape Measure how Our paper measuring tapes are ideal for the retail and wholesale fabric, furniture, fine apparel, and carpeting industries. Busy fabric stores, upholstery shops, and bespoke apparel salons appreciate the precise measurements they can achieve with our measuring tapes. Instead you should write -> The appropriate hospital ethics committee approved the study’s protocol. The building industry was the first major industry grouping in Australia to complete its change to metric, being completed by January 1976. [19] Australian 5 Metre measuring tape, with the markings entirely in millimetres.

Using standardised methods of measurement, including plotting measurements on a standardised growth chart, ensures accuracy and consistency when making referral decisions.

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 16in (40.6cm) and 19.2in (48.8cm). Find the closest cm marking and count the remaining number of mm markings to its right. For example, if there are 3 markings after 9 cm marking, then the measurement would be 9.3 cm. Metallic Tape is reinforced with copper wires to prevent stretching or twisting of fibers. They are available in many lengths but tapes of 20m and 30m are more commonly used. [24]

For example, if you want to find ⅝" on this tape measure, imagine that the inch is divided up into eight equal sections. ½" is 4/8", so look for the next ⅛" mark and you've found ⅝"!

The measuring tapes used for surveying purposes are classified in 4 types according to the material from which they are manufactured: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. [26] For example, under specific conditions the tolerances for 10m long tapes are:

Later, by the early 1870s, 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 1890s and early 1900s 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.)You will notice there is a little slit in the metal tab. This is so you can hook it over the head of a nail or screw to get an accurate measurement from a point in the middle of the board. Just be careful not to put a nail where the hole will be noticed! The modern idea of tape measures originated in tailoring with cloth tape used to alter or fix clothing. It wasn’t until carpenters adopted the Farrand Rapid Rule, patented by Hiram Farrand, that the tape measure became a staple of common usage. Ferrand’s design was later sold to Stanley Works. The sale of dual Metric/US Customary scale measuring tapes is slowly becoming common in the United States. For example, in some Walmarts there are Hyper Tough brand tapes available in both US customary units and Metric units. Unlike US rulers, of which an overwhelming majority contain both centimeter and inch scales, tape measures are longer and thus traditionally have had scales in both inches and feet & inches. 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 first patented long tape measure in the United States was granted U.S. patent #29,096 issued 10 July 1860 to William H. Paine of Sheboygan, Wisconsin, [3] 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. The objective of this study is to evaluate the precision -> The objective of this study is to evaluate the accuracy.
