4.47m/s²
That's 1.44× as hard as a family car pulling away, while a sports car launch is 1.23× harder. Kept up, that reaches 100 km/h in about 6.214 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 mph/s to m/s²
To convert mph per second to meters per second squared, multiply by 0.44704.
Example: 10 mph/s × 0.44704 = 4.4704 m/s².
In the other direction, 1 m/s² = 2.23694 mph/s.
