About these units
Short background on the units used in this conversion.
Acceleration of Gravity (g)
Standard gravity (g) is exactly 9.80665 m/s² — the nominal acceleration due to gravity at Earth’s surface, used as a reference in engineering.
Multiples of g express fighter-jet maneuvers, centrifuge ratings, and shock loads relative to everyday gravitational acceleration.
