About Metres and Kilometres
- Metres

Precision and common mistakes
The metre is defined exactly through the speed of light. The kilometre-to-metre relationship is exact. The calculator keeps the full catalogued factor internally and rounds only the displayed value.
- Do not confuse metres with square metres, which measure area, or cubic metres, which measure volume.
- Kilometres measure distance; kilometres per hour measure speed.
- Keep the original value and unit together when copying a result, especially when specifications use several measurement systems.
