About these units
Metric lengths step by powers of ten: 10 mm = 1 cm, 100 cm = 1 m and 1,000 m = 1 km. Imperial and US customary lengths have been defined exactly in metric since 1959: 1 inch = 2.54 cm, 1 foot = 12 inches = 30.48 cm, 1 yard = 3 feet = 0.9144 m and 1 mile = 1,760 yards = 1,609.344 m. Because these definitions are exact, the conversions on this page are exact up to rounding.
