=== Usage ===
This template calculates surface gravity ''g'' of a spherical body of the mass M and radius R:

<math>g=\frac{G*M}{R^2}</math>.

G is the [[gravitational constant]]. The template should be used in the following way:

<nowiki>{{Gr|M|R|PRE}}</nowiki>,

where M is body's mass in 1021 kg, R is radius in km and PRE is the number of digits after decimal dot in the result (default is 3). The result is expressed in m/s2.

Example (escape velocity of [[Titania (moon)|Titania]]): M=3.526{{E-sp|21}} kg, R=788.9 km.

g={{Gr|3.526|788.9}} m/s2.
