Reading the numbers

RPM

Revolutions per minute: a measure of rotational speed.

A little deeper

Engine RPM describes crankshaft speed, not road speed. The chosen gear and final-drive ratio change the relationship between engine rotation and wheel rotation.

Also known as: revolutions per minute · rev min · engine speed · ბრუნი წუთში · об/мин · обороты
