Convert between different distance and length units including metric, imperial, and scientific units.
This distance converter changes a length from one unit to another — miles to kilometers, meters to feet, inches to centimeters, yards to meters, and more. Type a value once and see the equivalent across every supported unit, which saves time when you are reading a map, following build plans, comparing running distances, or working with measurements that mix metric and imperial systems.
The conversions rely on the exact modern definitions of each unit. The international inch is defined as exactly 2.54 centimeters, and feet, yards, and miles all derive from it, while metric units chain cleanly from the meter. Because every factor traces back to the meter as the base unit, the results are precise rather than rounded shortcuts. The tool covers small units (millimeter, centimeter, inch), everyday units (foot, yard, meter), and large units (kilometer, mile), with enough decimal places to stay useful.
Everything is calculated in your browser as you type, so conversions are instant and continue to work offline after the page loads. Nothing you enter is transmitted to a server. Whether you need a quick "how many km is a 10-mile run" answer or precise engineering figures, you get the same reliable factors every time.
One mile equals approximately 1.609 kilometers. This derives from the exact definition of the inch as 2.54 centimeters, from which the mile is built.
Multiply the number of feet by 0.3048 to get meters, since one foot is defined as exactly 0.3048 meters. Enter the value and select feet and meters to do it automatically.
It handles common metric units (millimeter, centimeter, meter, kilometer) and imperial or US customary units (inch, foot, yard, mile), so you can convert freely between systems.
No. All conversions run locally in your browser, so the values you enter never leave your device and the tool works offline once loaded.
