Why symmetrical conversion?
How This Converter Works
Acceleration measures how quickly velocity changes. Standard gravity (g₀ = 9.80665 m/s²) is the most intuitive reference. Gal is used in geophysics, while km/h/s is used for vehicle performance specs.

FAQ
Frequently Asked Questions
1What is 1g of acceleration?
1g equals Earth's standard gravity: 9.80665 m/s² or 32.174 ft/s². A person experiencing 2g feels twice their body weight. Fighter pilots can briefly withstand 9g with a pressurised suit.
2What is the Gal unit of acceleration?
The Gal (named after Galileo) equals 0.01 m/s² or 1 cm/s². It is used in gravimetry and geophysics to measure small variations in gravitational acceleration across Earth's surface.
3How do I convert km/h/s to m/s²?
Divide by 3.6. So 36 km/h/s = 10 m/s². This unit describes how many km/h of speed are gained per second — useful for vehicle acceleration specs.
4What G-force can humans withstand?
Untrained humans can withstand about 4–5g briefly. Trained fighter pilots with G-suits can handle up to 9g for short periods. Sustained G-force above 5g causes loss of consciousness (G-LOC).
