About Speed & Velocity Conversion
Speed is a scalar quantity representing the rate of change of distance, while velocity is a vector quantity that includes direction. This converter handles speed units used in transportation, physics, and engineering.
Common Speed Units
- m/s: SI unit, commonly used in physics and engineering
- km/h: Standard unit for road speed limits worldwide
- mph: Miles per hour, used primarily in US and UK
- Knot: Nautical mile per hour, used in aviation and marine
- Mach: Speed relative to sound (≈ 343 m/s at sea level)
