Speed Unit Converter
Enter a speed value and choose its unit. This tool converts it into m/s, km/h, mph, knots, Mach, and ft/s simultaneously.
km/h → mph: multiply by 0.6214
mph → km/h: multiply by 1.609
m/s → km/h: multiply by 3.6
km/h → m/s: divide by 3.6
knots → mph: multiply by 1.151
mph → knots: multiply by 0.868
Mach → m/s: multiply by 343 (at sea level approx)
m/s → ft/s: multiply by 3.281
What is the Speed Conversion Tool & How to Use It? 🚗⚡
What is Speed Conversion?
Speed (or velocity) is the rate at which an object moves over time. Different units of speed are used across industries such as transportation, aviation, and physics. The Speed Conversion Tool allows you to quickly convert between different speed units with precision.
Some commonly used speed units include:
✅ Meters per second (m/s) – SI unit, used in physics and engineering.
✅ Kilometers per hour (km/h) – Common in road and rail transport.
✅ Miles per hour (mph) – Used in the US, UK, and road speed limits worldwide.
✅ Feet per second (ft/s) – Used in ballistics and aviation.
✅ Knots (kn) – Used in maritime and aviation industries.
✅ Mach (M) – Represents the speed of sound (1 Mach ≈ 343 m/s at sea level).
