Km/h per second to meters per second squared
Type a value in km/h/s to get it in m/s² instantly.
2.778m/s²
That's 2.8× as hard as a lift starting, while a family car pulling away is 1.12× harder. Kept up, that reaches 100 km/h in about 10 seconds.
What it means
How hard is that?
One g is the acceleration of gravity at the Earth’s surface, 9.80665 m/s² exactly.
The math
How to convert km/h/s to m/s²
To convert km/h per second to meters per second squared, multiply by 0.277778.
Example: 10 km/h/s × 0.277778 = 2.77778 m/s².
In the other direction, 1 m/s² = 3.6 km/h/s.

Km/h per second (km/h/s)
How many km/h the speed gains each second: the way car acceleration is often described.
Meters per second squared (m/s²)
The SI unit: speed rising by one meter per second, every second.
