Frequently asked questions

Use torque = hp × 5252 ÷ rpm. At 200 hp and 6000 rpm, torque is about 175 ft·lb.

It comes from the definition of horsepower and the constant for converting rpm to radians per minute. Power and torque curves always cross at 5252 rpm.

Torque is the turning force; power is how fast that work is done. Power equals torque times rotational speed.

It gives torque at the rpm and power you enter, usually crankshaft figures. Drivetrain losses reduce torque measured at the wheels.
