Speed and Velocity Conversions

Speed conversion is essential for transportation, sports, weather, and scientific applications. Our converter handles linear speeds across different unit systems.

Common Units

Meters per second (m/s) is SI standard. Kilometers per hour (km/h) for road speeds, miles per hour (mph) in US, knots for aviation and marine.

Transportation

Different modes use different units: cars (mph/km/h), aircraft (knots/mach), ships (knots), trains (mph/km/h), pedestrians (m/s).

Scientific Applications

Physics uses m/s, meteorology uses various units for wind speed, and astronomy uses much larger units for celestial objects.

Common Applications

Automotive and transportation, aviation and marine navigation, meteorology and weather, sports and athletics, and scientific research.

Conversion Tips

1 mph ≈ 1.6 km/h. 1 knot ≈ 1.85 km/h. Highway speeds: ~100 km/h or 60 mph. Walking speed: ~1.4 m/s or 5 km/h.
