For example, consider the galaxy UGC 2936:

#### How to Convert RPM to Linear Speed Sciencing

RPM Formula and Explanation RPM is a measure of the number of complete revolutions in a minute. For example, if a wheel is rolling so it completes one full revolution per second, in 60 seconds it will have completed 60 revolutions, and so it would be rotating at 60 RPM. An RPM formula that you can use to find the RPM in any situation is:

#### Linear Speed Formula (Rotating Object)

The linear speed of a point on a rotating object depends on its distance from the center of rotation. The angular speed is the angle that an object moves through in a certain amount of time. The angular speed has units of radians per second (rad/s). There are 2 radians in a full circle.
