G Force Calculator
Express an acceleration as a multiple of Earth's gravity.
G-force compares an acceleration to standard Earth gravity (9.81 m/s²).
The math behind it
g-force = acceleration ÷ 9.81. 1 g is what you feel standing still on Earth.
Worked example
29.43 m/s² → 3 g.
FAQ
How much g can people take?
Trained pilots handle ~9 g briefly; sustained high g causes blackouts.
