Put 56 kilowatts into the exact factor of 1.34102209 and you get 75.09723702 hp. Written out: 56 × 1.34102209 = 75.0972370173 horsepower, with no rounding applied until the final display.
56 kW is 75.1 mechanical horsepower and 76.14 metric PS. Put that through a 1,400 kg car at 80% drivetrain efficiency and the energy needed to reach 100 km/h — 540.1 kJ — takes about 12.1 seconds to deliver, which is a floor rather than a real figure because it ignores drag and traction limits.
The result lands almost exactly on 75 hp, which is why this is one of the conversions people remember. Plenty of people do this in their head: multiply by 1.3 instead of using the exact factor 1.34102209. At 56 that shortcut gives 72.8 horsepower, off by 2.297 horsepower or about 3.06%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.

56 kW- The quantity being converted
1.34102209- Exact horsepower in one kilowatt
75.09723702 hp- The converted result
How it works, step by step
- Start with 56 kilowatts.
- Apply the defined factor: one kilowatt is 1.34102209 horsepower, so multiply by that.
- Result: 75.0972370173 horsepower.
- Going the other way, divide rather than multiply — 75.09723702 hp ÷ 1.34102209 brings you back to 56 kW.
