Convert between eight length units
Millimeters, centimeters, meters, kilometers, inches, feet, yards, and miles are all supported, in any direction. Pick your starting unit as "From" and your target as "To" for a direct headline answer — for example, feet to centimeters, meters to feet, or miles to kilometers — and the reference table underneath shows the same measurement converted into all eight units at once, so you rarely need to run the calculator twice.
How the conversion works
Every unit is converted through meters as a common base: your value is multiplied by that unit's length in meters, then divided by the target unit's length in meters. That is the standard, exact way to convert between length units — 1 inch is defined as exactly 2.54 centimeters, 1 foot is 12 inches, 1 yard is 3 feet, and 1 mile is 5,280 feet — so the results here match any other correctly-built converter.
Common conversions this handles
Feet to centimeters or meters for furniture, shipping, or international spec sheets; inches to millimeters for parts and hardware; meters to feet for room or building dimensions; miles to kilometers for travel distances and race lengths; and yards to meters for fabric, lawns, or athletic fields. For a length-times-width area instead of a single conversion, use the Square Footage Calculator, which lets the length and width each use a different unit.
Runs entirely in your browser
Like every tool on this site, the conversion happens instantly in your browser as you type. Nothing you enter is sent anywhere, and there is no account to make.
Frequently asked questions
How do I convert feet to centimeters?
Set "From unit" to feet and "To unit" to centimeters, then enter your value. 1 foot equals exactly 30.48 centimeters, and the headline result updates as you type.
How many centimeters are in a meter?
100. Set the value to 1, "From unit" to meters, and read the centimeters row in the reference table — or set "From unit" to centimeters and "To unit" to meters for the reverse direction.
How do I convert miles to kilometers?
Set "From unit" to miles and "To unit" to kilometers. 1 mile equals about 1.60934 kilometers, so 5 miles converts to roughly 8.05 kilometers.
Can I see a value in every unit at once instead of picking one target unit?
Yes — the table below the headline result always lists the entered value converted into all eight supported units, regardless of which "To unit" is selected.
