How to Convert Between Speed Units

Formula

All speeds are first converted to m/s, then from m/s to the target unit.

Speed conversion is important for travel, aviation, marine navigation, and physics. This converter supports all major speed units used worldwide.

Internally, all speeds are converted to meters per second (m/s), the SI base unit for velocity, ensuring accurate results.

Common use cases:

  • Converting vehicle speed limits between countries
  • Aviation and marine navigation speed conversions
  • Physics velocity calculations
