Centrifugal Force Spin Rate Calculator

This tool calculates the spin rate required (for example on a space station) at a specific distance away from the center, to produce a given equivalent artifical gravity

Enter the radius (distance from the center) of the location, and the desired centrifugal force (artificial gravity required).

From these two inputs the required rpm (revolutions per minute) to achieve this will be calculated.

Acceleration due to a gravity, is usually specificed in m/s/s, the magniture of this is also the same figure as the force per 1 kg that an object experiences (N/kg).

Standard gravity is 9.80665 m/s/s = 1 G, 9.80665 N/kg = 1 G

For Earth like artifical gravity we would want an acceleration of 9.80665 m/s/s, which is standard gravity, which is caused by a force of 9.80665 N/kg.

To calculate any variant of G (standard gravity just multiply 9.80665 by that factor.

E.g.

1 G: (100 % gravity) is 1 X 9.80665 m/s/s = 9.80665 m/s/s.
0.5 G: (50 % gravity) is 0.5 X 9.80665 m/s/s = 4.903325 m/s/s.
