## RPM to G Force Formula:

RPM to G Force Conversion calculates the centrifugal force experienced by an object

in rotation, expressed as multiples of Earth’s gravity (g). This conversion uses the

rotational speed (RPM) and the radius of rotation to determine the force exerted on

objects.

G Force, GF(g) is calculated using the radius of rotation, r(m) in metres and the

rotational speed, RPM in Revolutions Per Minute, to find the centrifugal acceleration,

which is then divided by the standard acceleration due to gravity, 9.81m/s2, to

convert it into multiples of Earth’s gravity (G).

G Force, GF(g) = ( ( r(m) * 6.28 / 60 * RPM)2 / r(m) / 9.81)

GF(g) = G force, g.

r(m) = radius of rotation in metres, m.

RPM = rotational speed in revolutions in speed, RPM.

### RPM to G Force Calculation:

1. Calculate the G force experienced by an object spinning at 1500 RPM at a radius

of 0.05 metres from the center of rotation.

Given: r(m) = 0.05m, RPM = 1500.

G Force, GF(g) = ( ( r(m) * 6.28 / 60 * RPM)2 / r(m) / 9.81)

GF(g) = ( ( 0.05 * 6.28 / 60 * 1500) / 0.05 / 9.81)

GF(g) = 2465.13 / 9.81

GF(g) = 251.219g

1. Find the RPM needed to generate a G Force of 4g at a radius of 0.5 metres.

Given: r(m) = 0.5m, GF(g) = 4g.

G Force, GF(g) = ( ( r(m) * 6.28 / 60 * RPM )2 / r(m) / 9.81)

RPM = 60 * √(GF(g) * r(m) * 9.81) / r(m) * 6.28

RPM = 60 * √( 4 * 0.5 * 9.81 ) / 0.5 * 6.28

RPM = 60 * 4.43 / 3.14159

RPM = 84.6.
