How It Works
How to Convert g-Force to m/s²
Formula
m/s² = g x 9.80665
The standard acceleration due to gravity (g) is defined as exactly 9.80665 m/s². This value was adopted by the 3rd General Conference on Weights and Measures in 1901 as a standard reference. One g is the nominal gravitational acceleration at sea level on Earth.
Typical Accelerations
Worked Example
Convert 1 g to m/s².
- 01Standard gravity: 1 g = 9.80665 m/s² (exact definition)
- 02m/s² = 1 * 9.80665 = 9.80665 m/s²
- 03In imperial: 1 g = 32.174 ft/s²
Frequently Asked Questions
Why is g defined as 9.80665 and not some rounder number?
The value 9.80665 m/s² was chosen as a standard because it closely approximates the actual gravitational acceleration at sea level at latitude 45°. It was internationally adopted in 1901.
Is g-force actually a force?
Despite the name, g-force is a measure of acceleration, not force. It expresses acceleration relative to the standard gravitational acceleration. Force is obtained by multiplying g-force by mass (F = m*a).
How many g can a human withstand?
Trained pilots with g-suits can withstand 9 g for brief periods. Untrained individuals may lose consciousness above 4-5 g. The duration and direction of the acceleration both matter significantly.
