The foot is a unit of length in the imperial and US customary systems of measurement. It is defined as exactly 0.3048 meters. The foot is subdivided into 12 inches.
An inch is 1/12 of a foot and is exactly 2.54 centimeters. Inches are commonly used in the United States for measuring shorter distances, screen sizes, paper dimensions, and human heights.
The relationship between feet and inches (1 foot = 12 inches) has been standardized since 1959 when the International Yard and Pound Agreement defined the exact metric equivalents.
Multiply the number of feet by 12 to get inches. For example, 5 feet = 5 × 12 = 60 inches.
Divide the number of inches by 12 to get feet. For example, 72 inches = 72 ÷ 12 = 6 feet.
There are exactly 12 inches in 1 foot. This relationship is standardized and used worldwide in countries that use imperial measurements.
Multiply the feet by 12 and add the inches. For example, 5 feet 8 inches = (5 × 12) + 8 = 60 + 8 = 68 inches total.
1 foot = 30.48 cm (exactly), and 1 inch = 2.54 cm (exactly). To convert to metric, multiply feet by 30.48 or inches by 2.54.
The 12-inch foot comes from ancient Roman and Anglo-Saxon measurement systems. Twelve is highly divisible (by 2, 3, 4, and 6), making it practical for construction and commerce.
