Standard gravity is a reference constant equal to 9.80665 m/s², used to express acceleration relative to Earth's gravitational pull.
Defined in 1901 by the International Committee for Weights and Measures as a fixed reference value, independent of local gravity variations.
Measurement system: International reference constant (non-SI, defined value). SI equivalent: 1 g = 9.80665 m/s².
