The term 'rpm' stands for "revolutions per minute." It is a measure of the frequency of rotation, specifically how many complete turns an object makes in one minute. This measurement is commonly used in various fields, such as engineering, physics, and music, to indicate the speed of rotating devices, like motors, wheels, or turntables.
The term 'rpm' is derived from the words "revolution," which comes from the Latin "revolutio," meaning a turning over or rolling back, and "minute," from the Latin "minuta," meaning small. The abbreviation 'rpm' has been widely adopted in technical contexts since the 20th century.
