Usage

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

<math>v2=\frac{G*M}{R^2}</math>.

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

{{Gr|M|R|pre}},

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. The result is expressed in m/s2.

Example (escape velocity of Titania). M=3.526 kg. R=788.9 km:

v2=0.378 m/s2.
