Useful relationships
1 g = 9.80665 m/s² exactly.
1 Gal = 1 cm/s² = 0.01 m/s².
1 mGal = 10⁻⁵ m/s².
1 ft/s² = 0.3048 m/s² exactly.
1 mph per second = 0.44704 m/s² exactly.
Acceleration can be negative. A negative value represents acceleration opposite the chosen positive direction; it is often called deceleration when it reduces speed.
