A foot (ft) is a unit of length in the imperial and US customary systems. Standardized as exactly 0.3048 meters, one foot contains 12 inches.
The foot has its own history, which varies from country to country. The unit differed across cultures (including Rome, Greece, England, China, France, and Japan), often based on anthropomorphic measures such as the cubit, hand, span, digit, or barleycorn.
What Is An Inch?
An inch (in) is a unit of length equal to 1/12 of a foot. Defined as exactly 25.4 millimeters, it is a foundational measurement in the US, Canada, and the UK.
The word inch comes from the Latin uncia (“twelfth part”).
