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). Whilst the seasoned professionals amongst you will no doubt be fully aware how to read the various markings on your tape, there will be amateurs, enthusiasts or those just starting off in their careers who aren’t yet so knowledgeable. We regularly get asked the question “how do you read a tape measure”. In response to our customers, therefore, we’ve put together this simple guide that explains just that! If you look closely at your tape measure, you’ll see that the hook at the end has a few unique qualities. One is that it should be slightly loose on its rivets. This allows it to slide in or out to allow for accuracy whether taking an inner or outer measure. This also means that the first inch on a tape measure is inaccurate by the amount of that movement (usually 1/16 inch). So if you need to take the measure of a small item, use a section further up the tape.

What's more, some tape measures (regardless of expense or quality) can feature steel blades with relatively sharp edges. They may not feel sharp at first but it can be a very different story when travelling at speed. In 1947, the Swedish engineer Ture Anders Ljungberg began developing an improved version and in 1954 the TALmeter was introduced. It features edges at both the end of the tape and the mouth to cut marks so measures (including arcs) can be transferred without reading the scale, as well as a fold-out metal tongue at the rear, also with an edge, to be used when taking internal measures. The tape has three scales: the normal metric, the internal scale and a diameter scale used for instance to measure sheet metal to be rolled into a cylinder of a certain diameter. It was produced by his own company T A Ljungberg AB until 2005, when it was bought by Hultafors in 2005, who retained the name "Talmeter" for the product they now refer to as a märkmeter (marker-meter). [9] The training which the measurers underwent and probably the pre and post training reliability as a measure of the effectiveness of the training Reply: We have performed analysis of combination between 2 measurements with the best precision and reliability. The result was shown in table2. The combination did not improve precision and the reliability was the same. 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:It is a good practice to use active voice instead of passive voice which you have throughout the manuscript. As an example: The study’s protocol was approved by the appropriate hospital ethics committee. Instead you should write -> The appropriate hospital ethics committee approved the study’s protocol. 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. Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters) A second tape measure design is what is called the long tape. These are cased tape measures with tapes of up to 200 m in length. It is designed for engineers and builders. Long tapes, instead of being returned by a spring, are usually returned by hand crank. Because surveying was usually done in rods, surveyors used long tapes of 2 rods (1.01 m, 33 feet), and 4 rods (2.01 m, 66 feet). Surveyors also used 49 + 1⁄ 2 feet of a 50-foot tape for 3 rods and 99 feet of a 100-foot tape measure for 6 rods The first record of people using a measuring device was by the Romans using marked strips of leather, but this was more like a regular ruler than a tape measure.

Instead you should write -> The appropriate hospital ethics committee approved the study’s protocol. The tape measure shown above goes down to the 1/32nd of an inch, but most only show lines for 1/16th and larger. If you're not sure about yours, count the lines between one and two inches (including the 2" mark). 32 lines = 1/32" spacing. 16 lines = 1/16" spacing. 8 lines = ⅛" spacing. Worth the Money: Stanley Tape Measure". Popular Mechanics. 20 March 2014 . Retrieved 15 March 2023.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]. Everyone should own a quality tape measure; it’s one of the three all-around tools every homeowner should have.

Verify that the printout is accurate and the correct size by measuring a sheet of printer paper. A standard piece of US letter paper measures 8.5″ x 11″. Let's start simple. The distance from the 2" to 3" marker is, of course, 1". From the inch mark to the ⅛" mark is ⅛". 1" + ⅛" = 1 ⅛".

Hand Measuring

Tape measures come in both Imperial Units (inches and feet) and metric (centimeters and meters), featuring unit breakdowns for further accuracy. Specialized versions can include markings that cover truss lengths for roofing and stud intervals for housing. 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!
