Horsepower
Convert hp and kW, find power from torque and RPM, and estimate engine power from a quarter-mile run.
What to find:
Horsepower is a unit of power outside SI. Metric horsepower (PS) equals 735.5 W, while mechanical horsepower (hp) used in the US equals 745.7 W.
Power from torque
P (kW) = M (N·m) · n (RPM) / 9549
