How it works

Every unit is defined by its size in meters, and a conversion multiplies by the ratio of the two sizes:

value in target unit = value × (size of source unit ÷ size of target unit)

The line under the result shows that ratio for the units you picked, for example 1 ft = 0.3048 m. To convert by hand, multiply by it.

Unit In meters Definition
Millimeter (mm) 0.001 1/1000 of a meter
Centimeter (cm) 0.01 1/100 of a meter
Kilometer (km) 1,000 1,000 meters
Inch (in) 0.0254 Exactly 2.54 cm
Foot (ft) 0.3048 12 inches
Yard (yd) 0.9144 3 feet
Mile (mi) 1,609.344 1,760 yards, 5,280 feet
Nautical mile (nmi) 1,852 Defined internationally

All of these factors are exact, so the only rounding happens when the result is displayed (up to 10 decimal places).

Examples

  • Height. 180 cm ÷ 2.54 = 70.87 in = 5 ft 10.87 in. The other way, 5′ 10″ is 70 × 2.54 = 177.8 cm.
  • Running. A 10 km race is 6.214 miles, and a marathon (42.195 km) is 26.219 miles.
  • Screens. A 27-inch monitor measures 27 × 2.54 = 68.58 cm across the diagonal.
  • Rooms. A 12 ft wall is 12 × 0.3048 = 3.6576 m long.

Frequently asked questions

How many centimeters are in an inch?

Exactly 2.54. Since 1959 the inch has been defined as 25.4 millimeters, so every inch–metric conversion is exact rather than approximate.

How do I convert my height from centimeters to feet and inches?

Divide by 2.54 to get inches, then take out whole feet (12 inches each). 180 cm is 70.87 inches, which is 5 feet and 10.87 inches, usually written 5′ 10.9″.

How many feet are in a mile?

5,280 feet, or 1,760 yards. A mile is exactly 1,609.344 meters.

What is the difference between a mile and a nautical mile?

A nautical mile is 1,852 meters, about 15% longer than a statute mile (1,609.344 m). It is used at sea and in aviation because it corresponds to one minute of latitude.
