Inch - the commonly used unit of length in US and UK

The inch is a unit of length in the British imperial and the United States customary systems of measurement. The word inch is derived from the Roman uncia ("twelfth") and is occasionally used to translate analogous units in other measuring systems, which are commonly considered to be derived from the width of the human thumb.

In the past, standards for the precise length of an inch fluctuated, but with the adoption of the international yard in the 1950s and 1960s, the inch has been based on the metric system and defined as exactly 2.54 cm.

Though scientists frequently prefer SI prefixes for factors of ${10}^3$, such as milli- and kilo, for many physical quantities, the centimeter remains a practical unit of length for many common measures. A centimeter is roughly the width of an average adult's fingernail.
