The acceleration of freefall, the acceleration at which an object would fall under the force of gravity in a vacuum. The value will vary according to the distance from the centre of gravity. The value quoted is the internationally accepted value.

g = 9.80665 ms-2

In imperial units:

g = 32.174 ft s-2
