What is a revolution?
A revolution is one complete turn, equal to 360 degrees or 2π radians. It is the unit you count in when something spins.
Engine and motor speeds are given in revolutions per minute, or RPM, and machinery gearing is worked out in whole and part revolutions. Converting revolutions to degrees is just multiplying by 360.
In writing, the revolution is usually shortened to "r". One revolution is 360 degrees, and that ratio is what every number on this page is built from.
