Use the m/s² to km/h/s Converter
m/s² to km/h/s formula and what each symbol means
km/h/s = m/s² × 3.6
| Symbol | Meaning |
|---|---|
| m/s² | Meter per second squared |
| km/h/s | Kilometer per hour per second |
m/s² to km/h/s examples
1 m/s²
1 m/s² × 3.6 = 3.6 km/h/s.
10 m/s²
10 m/s² × 3.6 = 36 km/h/s.
100 m/s²
100 m/s² × 3.6 = 360 km/h/s.
m/s² compared with km/h/s
One m/s² is 3.6 times as large as one km/h/s, so your number gets bigger when you convert m/s² to km/h/s and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About m/s² and km/h/s
Meter per second squared (m/s²): The SI unit of acceleration. Kilometer per hour per second (km/h/s): A speed change of 1 km/h each second, about 0.27778 m/s².
Where m/s² to km/h/s conversions are used
Aviation and amusement rides quote the g-load that passengers feel. Vehicle performance and crash tests use g-force.
How to calculate m/s² to km/h/s step by step
- Enter the value in m/s² (the starting unit).
- Multiply by 3.6, because 1 m/s² = 3.6 km/h/s.
- The product is the value in km/h/s. To go back, divide by 3.6 or multiply by 0.2777778.
