Speed Conversion Reference
Metric Units
- Meter per Second (m/s): SI unit of speed. 1 m/s = distance of 1 meter traveled in 1 second. Standard unit in physics and science.
- Kilometer per Hour (km/h): 1 km/h = 0.277778 m/s. Most common unit for road speeds in most countries worldwide.
- Kilometer per Second (km/s): 1 km/s = 1000 m/s. Used for very high speeds like spacecraft and astronomical objects.
- Centimeter per Second (cm/s): 1 cm/s = 0.01 m/s. Used in scientific measurements and slow-speed applications.
Imperial/US Units
- Mile per Hour (mph): 1 mph = 0.44704 m/s = 1.60934 km/h. Standard speed unit in the United States and United Kingdom.
- Mile per Second (mi/s): 1 mi/s = 1609.344 m/s. Used for very high-speed calculations in physics and engineering.
- Foot per Second (ft/s): 1 ft/s = 0.3048 m/s. Used in engineering and ballistics calculations.
- Foot per Minute (ft/min): 1 ft/min = 0.00508 m/s. Used for slow-speed industrial applications and conveyor systems.
- Inch per Second (in/s): 1 in/s = 0.0254 m/s. Used for precision measurements in manufacturing and material testing.
Aviation & Maritime Units
- Knot (kn): 1 kn = 0.514444 m/s = 1.852 km/h. One nautical mile per hour. Standard unit in aviation and maritime navigation.
- Mach (Ma): 1 Ma ≈ 343 m/s = 1235 km/h at sea level. Speed relative to the speed of sound. Varies with temperature and altitude.
Special Units
- Speed of Light (c): c = 299,792,458 m/s. The maximum speed at which all energy, matter, and information can travel in the universe.
- Speed of Sound: ≈ 343 m/s = 1235 km/h at sea level (20°C). Varies with temperature, pressure, and medium.
Quick Reference Conversions
- 1 m/s = 3.6 km/h = 2.23694 mph = 1.94384 kn
- 1 km/h = 0.277778 m/s = 0.621371 mph = 0.539957 kn
- 1 mph = 0.44704 m/s = 1.60934 km/h = 0.868976 kn
- 1 knot = 0.514444 m/s = 1.852 km/h = 1.15078 mph
- 1 Mach = 343 m/s = 1235 km/h = 767 mph (at sea level, 20°C)
