Foot

What Is a Foot?
A foot (symbol: ft) is a traditional length unit in the Imperial and U.S. customary systems. Since 1959, it’s been exactly 0.3048 m. Each foot contains 12 inches, and three feet equal one yard.

Historical Background
Across ancient and medieval cultures—from Greek and Roman to English and Chinese—the “foot” varied in length (roughly 250 mm to 335 mm), often based on body measurements like the human foot or span. To eliminate regional discrepancies, an international agreement in 1959 fixed the foot at precisely 0.3048 m.

Where It’s Used Today
Feet remain standard in the United States, Canada, and the United Kingdom for everyday measurements: room dimensions, personal height, sports fields, and aviation altitudes. On our site, you can instantly toggle between feet and inches or metric values.

Inch

What Is an Inch?
An inch (symbol: in) is another Imperial/U.S. customary length unit. Officially defined in 1959 as exactly 25.4 mm, there are 12 inches in a foot and 36 inches in a yard.

Historical Background
The name “inch” comes from the Latin uncia (“one-twelfth”), originally meaning one-twelfth of a Roman foot. Early standards included three barleycorns end-to-end or the average thumb width; later, the inch was standardized against the international yard.

Where It’s Used Today
Inches are still used in the U.S., Canada, and U.K. for construction, hardware sizing, and display diagonals in electronics. Our quick converter lets you switch seamlessly between inches, feet, and metric units.
