G

(Metric) As an upper-case prefix, G-, see giga-, e.g. GJ = gigajoule.

mass (Metric) As g, see gram, also prefixed variously, as in mg = milligram(s); see SI alphabet. Strictly lower-case.

acceleration As g, gravity, a representative value of Earth's gravitational acceleration at sea level, often taken as 10 m·s^-2 (see standard gravity). Used, with appropriate positive and negative multipliers, for acceleration generally, especially as experienced in accelerating, braking, turning, and colliding vehicles. Hence g scale. See also G; G scale.

It should be noted that the (usually italicized) symbol g stands for the acceleration due to gravity in a general sense, too, i.e. the value particular to a location and altitude.

plane angle France As ^g, but used in an elevated position, i.e. ^g, see grade.

fundamental constant As G, see Newtonian constant of gravitation.

electromagnetics As G, see gauss.
