Everyone knows what is a measuring tape and how to use it, but almost none of us have any idea of the small markings and numerals that are subtly placed in between the numbers and dashes. Today, we are going to solve that mystery and tell you what those markings are and how to use them.
We start off with the obvious details: the larger numbers at the top represent inches, while the smaller numbers on the bottom of the tape indicate centimeters.
These diamonds appear at the 19.2-inch mark and allow the construction workers to make five trusses in an eight-foot space. Truss layouts or items are usually eight feet in length, and when you divide 8 feet (96 inches) into five, you get 19.2 inches.
This accuracy would be difficult to complete without these marks because of the decimal point. Hence, the diamonds are placed to end the hassle altogether. While the presence of these diamonds may seem trivial to the average person; it is vital for the construction workers as most of the American construction materials come in lengths of eight feet.
