How many inches are in four feet?

There are 48 inches in four feet. One foot contains 12 inches, so multiplying 4 feet by 12 inches per foot gives 48 inches.

The foot is a traditional unit in the British imperial and United States customary systems. Its length varied historically across regions, but the modern international foot has been fixed at exactly 0.3048 meters since an international agreement in 1959. The inch remains its twelfth part.

A common mix-up is confusing feet with yards. One yard equals three feet, so four feet is 1⅓ yards—not four yards. In metric terms, four international feet equal 1.2192 meters, or 121.92 centimeters.

The plural form is normally “feet,” although “foot” can appear after a number in informal descriptions of height, such as “six foot tall.”
