Convert length and distance across metric and imperial
Switch between millimetres, centimetres, metres, kilometres, inches, feet, yards, and miles in one place. Enter a value once and every other unit updates, so you can move between a metric spec sheet and imperial tooling without chaining separate conversions.
For DIY, travel, and schoolwork
Measure up furniture in centimetres but buy timber in feet, read a running route in kilometres when you think in miles, or check a homework answer in seconds. Conversions run locally in your browser, so there's no rounding surprise from a server round-trip and nothing you type ever leaves the page.
