Foot

A foot (plural: feet) is a unit of length commonly used in the United States, the United Kingdom, and some other countries. One foot equals 12 inches or about 0.3048 meters. Feet are often used to measure height, room dimensions, and short distances. For example, a person might be 5 feet 8 inches tall. The abbreviation for foot is "ft". Although many countries use the metric system, feet remain popular in daily life and construction in countries using the imperial system.
