What is a speed converter?
Speed measures how fast an object moves, expressed as distance traveled per unit of time. Common units include kilometers per hour (km/h), miles per hour (mph), meters per second (m/s), and knots (nautical miles per hour).
Common uses for speed conversion
- Driving — Converting speed limits between mph and km/h when traveling internationally
- Aviation — Using knots for airspeed and converting to ground speed in km/h or mph
- Marine Navigation — Converting knots to km/h or mph for boating
- Physics & Engineering — Working with meters per second in scientific calculations
- Athletics — Converting running pace and speed between metric and imperial
All speed units
- Meters per Second (m/s)
- Kilometers per Hour (km/h)
- Miles per Hour (mph)
- Feet per Second (ft/s)
- Feet per Minute (ft/min)
- Millimeters per Hour (mm/h)
- Inches per Hour (in/h)
- Knot (kn)
- Mach (Ma)
- Speed of Light (c)
Tips for speed conversion
- 1 mph ≈ 1.609 km/h — multiply mph by 1.6 for a quick km/h estimate
- 1 knot = 1.852 km/h = 1.151 mph
- The speed of sound ≈ 343 m/s = 1,235 km/h = 767 mph at sea level
