Inch is a globally accepted unit of measurement. An inch is defined as 1/12th of a foot or approximately 2.54 centimetres. This benchmark is used for measuring lengths including height, width, length, diameter, etc. The symbol that denotes inches is ("). For example, 10 inches will be written as 10". Inches are often expressed in fractions to get more accurate measurements. Some of the fractions are 1/2, 1/4, 1/8, 1/16.
Inches are measured using tools including rulers, tape measures and callipers. Inches are commonly used in the fields of architecture and engineering to measure buildings and construction projects precisely.
The word inch is derived from the Latin uncia, a Roman unit of length, which means the “twelfth part”. In Japan, it is used for measuring electronic parts and most commonly the display of the screens. This unit is most used in the fields of engineering, architecture, and many times in real estate. In the UK, the inch along with the foot is used as a primary unit for road signs and another related measurement of distance. The secondary purpose includes the measurement of the metric divisions. Canada, Japan, India, and the United States are the common countries using this unit of measurement.
