Gravedad Estándar

Definición

La aceleración gravitacional nominal en la superficie terrestre, definida exactamente como 9,80665 m/s², utilizada para definir el kilogramo-fuerza y estandarizar las mediciones de peso.

Explicación

Actual surface gravity varies from 9.764 m/s² at the equator to 9.863 m/s² at the poles due to Earth’s rotation and non-spherical shape. The standard value of 9.80665 m/s² was adopted in 1901 to provide a consistent reference for force unit conversions: one kilogram-force equals exactly 9.80665 newtons. Spring scales calibrated for standard gravity will read about 0.5% high at the equator.
