![]() There some other markings, which appear particularly on tape measures sold in the United States. At three feet, for example, it would measure 36 inches. On the other edge the inches will keep numbering incrementally, so 1ft 2 inches will register as 14 inches, and so on. Sometimes you will find that on one edge that after the foot marker, the inches will increase again by single digits to reach 12 for a the next foot. As we know, 12 inches make up a foot, and these are marked with 1F, 2F, 3F, and so on. The ½ inch is marked with a yet longer hash, and then each inch is marked with a hash that runs across the width of the measure, and a number. These are longer again, and 2/8ths, 4/8ths, and 6/8ths are marked as quarter inches. The next is the 1/8th of an inch with a slightly longer hash mark. The smallest unit marked is the 1/16th of an inch. The Imperial measure used extensively in the US, is split to feet, inches and fractions of an inch. Imperial measurement can be a bit tricky, especially or those who have been brought up using Metric measurement. A hundred centimeters make up a meter (m), which is again clearly marked on a tape measure with a hash mark that will extend across the width. Every tenth centimeter is highlighted, so they can be easily picked out. Ten millimeters make up a centimeter (cm) and these are marked with a number, and a bigger hash mark. As they are so small, they are generally not individually numbered on tape measures. These are the smallest unit on the tape measure scale, and are also marked with the smalles hash mark along the edge. Building and construction practice calls for all measurements to be made in millimeters (mm). Metric measurement is the simplest system of use. Until recently in the US, for example, all tape measures were in Imperial units, however the dual standard option is becoming more widely available. ![]() In some countries such as the UK, tape measures have both Imperial and Metric measurement markings. Unfortunately, there is no universal standard of measurement, so tape measures around the world are made with two scales of measurement, Imperial, which is split into feet and inches, and Metric, made up of millimeters, centimeters, and meters. When you go to the local home improvement store, and see the vast array of tape measures on display, you’re probably going to say that they are all alike. The concave metal gives rigidity which means the measure can stand straight up to six feet. Over the years it was refined, but it was not until the 1920s that the first metal tape measures we know today began to appear. We have to thank William Bangs of Connecticut for this handy device, as he was the man who patented the first tape measure in 1864. The tape measure may appear to be simple on the surface, but it can cause no end of trouble for some people, not to mention the heartache when a project fails. That’s why you’ll find a tape measure in every tool kit, it’s become one of the most useful and most misread devices on the plant. ![]() It doesn’t matter if you are a craftsman or a weekend DIYer, a project is sure to go wrong if you don’t get the measurements right.
