Kilowatts to Horsepower
A kilowatt is 1,000 watts, used to rate electric motors, appliances, and EV charging speeds. Mechanical horsepower, about 745.7 watts, is the traditional unit for rating car and engine power in the US and UK. 1 kW equals ≈1.34102 hp, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to power, measured here against power's base unit (W) — every other power unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
hp = kW × ≈1.34102
kW = hp × ≈0.7457
Worked example: 5 kW × ≈1.34102 = ≈6.70511 hp.
