How the Length Converter works

Enter a length, choose the unit you have and the unit you want. The result updates as you type, and the table under it shows the same length in every unit — handy when you need centimeters, inches and feet at once.

Every unit is defined in meters. Imperial units use the international definitions agreed in 1959: one inch is exactly 2.54 cm, so one foot (12 inches) is exactly 0.3048 m and one mile is exactly 1,609.344 m.

6 × 30.48 = 182.88 cm

A marathon in miles

42.195 km ÷ 1.609344 = 26.22 mi

100 meters in yards

100 ÷ 0.9144 = 109.36 yd

Frequently asked questions

How do I convert a height like 5 ft 9 in?

Turn it into inches first: 5 × 12 + 9 = 69 in. Then convert 69 inches to centimeters: 69 × 2.54 = 175.26 cm.

How many centimeters are in an inch?

Exactly 2.54. It's a definition, not a rounded measurement, so inch-to-centimeter conversions are exact.

What's the difference between a mile and a nautical mile?

A (statute) mile is 1,609.344 m. A nautical mile, used at sea and in aviation, is 1,852 m — about 1.15 miles.
