Acceleration of Gravity (symbol g)

By the International Gravity Formula,
<math>g = 978.0495 [1 + 0.0052892 sin<sup>2</sup>(p) - 0.0000073 sin<sup>2</sup> (2p)] </math>
centimeters per second squared at sea level at latitude p. See gravity.
The standard value of gravity, or normal gravity, g, is defined as g
centimeters per second squared, or 32.1741 feet per second squared. This value corresponds closely to the International Gravity Formula value of g at 45° latitude at sea level.
