About meters per second and kilometers per hour
Meter per second (m/s)
A meter per second is the SI unit of speed. It is used in physics, engineering and wind or flow speeds.
Kilometer per hour (km/h)
A kilometer per hour is 1/3.6 of a meter per second. It is used for road speed limits and vehicle speeds in most countries.
Both are units of speed; the base unit used internally is m/s.
Notes
- The knot is one international nautical mile per hour (1852/3600 m/s ≈ 0.514444 m/s).
- Negative values are accepted to represent velocity along a signed axis.
m/s to km/h FAQs
How do I convert meters per second to kilometers per hour?
Multiply the number of meters per second by 3.6 to get kilometers per hour. For example, 25 m/s × 3.6 = 90 km/h.
How many kilometers per hour are in one meter per second?
1 m/s = 3.6 km/h and 1 km/h = 0.2777777778 m/s. To go the other way, use the kilometers per hour to meters per second converter.
How many kilometers per hour are in 40 meters per second?
40 m/s = 144 km/h, rounded to 6 significant digits. Change the value in the converter above for any other amount.
How many kilometers per hour are in 343 meters per second?
343 m/s = 1234.8 km/h, rounded to 6 significant digits.
Is the m/s to km/h conversion exact?
Yes. The factor 3.6 follows directly from the unit definitions (A meter per second is the SI unit of speed; a kilometer per hour is 1/3.6 of a meter per second), so the only rounding is in the digits you choose to display.
What is the difference between meters per second and kilometers per hour?
A meter per second is the SI unit of speed. It is used in physics, engineering and wind or flow speeds. A kilometer per hour is 1/3.6 of a meter per second. It is used for road speed limits and vehicle speeds in most countries.
