Supported Units
Converts between metric units (millimeter, centimeter, meter, kilometer) and imperial/US units (inch, foot, yard, mile). All conversions go through meters internally: each unit has a fixed meters-per-unit ratio (e.g. 1 inch = 0.0254 m, 1 mile = 1609.34 m), so converting unit A to unit B is value × (A's ratio ÷ B's ratio).
Common Uses
- Converting product dimensions between metric and imperial for international listings.
- Checking height or distance measurements given in an unfamiliar unit.
- Converting recipe or construction measurements.
