Enter once and see every supported unit
Enter a value and choose the source unit, then the page converts it into metric units such as kilometers, meters, decimeters, centimeters, and millimeters, plus mile, yard, foot, inch, and nautical mile. Each result is shown as a separate card so you can compare the scale quickly.
Local browser math with copyable results
The conversion uses the unit factors from the shared unit library, converts through meters as the base unit, and formats cards with up to seven significant digits. Tap a result card or its copy button to copy the displayed value; empty, zero, or invalid input shows placeholder results instead of a copyable conversion.
