What it means

How much power is that?

Power is torque times angular speed, so a torque figure alone says nothing about power. Quoted peak torque and peak power almost never occur at the same revs.

The math

How to convert lb·ft to hp

Power is torque times rotational speed: kW = N·m × rpm ÷ 9549, or in US units hp = lb·ft × rpm ÷ 5252. The figures below are at the engine speed selected above.

Example: 300 lb·ft = 85.6798 hp.

The table below is at 1,500 rpm, idling along.
