Usage

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

$g=\frac{G*M}{R^2}$.

G is the ثابت گرانش. 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 (default is 3). The result is expressed in m/s².

Example (escape velocity of تیتانیا (ماه)): M=3.526الگو:Esp kg, R=788.9 km.

g=الگو:Gr m/s².
