Hydraulic Motor or Engine Torque

IMPERIAL

Where:

T = Torque in pounds feet

HP = Horsepower

RPM = Engine speed in revolution per minute

Example:

What is the torque of an engine that develops 40 HP at 2500 RPM?

METRIC

Where:

T = Torque in newton metre (N m)

P = Power in watts (W)

RPM = Engine speed in revolutions per minute

Example:

What is the torque of an engine that develops 30,000 W at 2500 rpm?
