Question: What do you mean by Foot ?

Answer:

A Foot is a unit of length, roughly corresponding to the length of an average person’s foot. It is about 30 centimetres.

A tall person is about 6 feet high. 6 feet is sometimes written 6’. A foot is subdivided into 12 inches. There are 5280 feet in a mile. The international standard symbol for a foot is ft.

In some cases, the foot is denoted by a prime, which is often approximated by an apostrophe, and the inch by a double prime. For example, 2 feet 4 inches is denoted as 2'4''. This use can cause confusion, because the prime and double prime are also international standard symbols for arcminutes and arcseconds.
