How it works
Meter, centimeter and kilometer are units of the International System (metric), while mile, foot and inch belong to the imperial system, used mainly in the United States and the United Kingdom. One meter equals 100 centimeters. The meter is defined as the distance light travels in a vacuum in 1/299,792,458 of a second. Since 1959, the inch has been exactly 2.54 cm, and the foot equals 12 inches (30.48 cm). The mile, at 1,609.34 meters, is still used on road signs and for distances in the United States and the United Kingdom. Useful references: a marathon is 42.195 km, about 26.2 miles; 5 km is about 3.1 miles. A height of 1.75 m is about 5 feet 9 inches. To convert combined feet and inches, convert each part and add them up.
