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 hp to kW
To convert horsepower to kilowatts, multiply by 0.7457.
Example: 300 hp × 0.7457 = 223.71 kW.
In the other direction, 1 kW = 1.34102 hp.
