Converting 72 kilowatts gives 96.55359045 hp. One multiplication does it — 72 × 1.34102209 = 96.5535904508 horsepower — and because the factor is defined rather than measured, that answer will not drift over time.
72 kW is 96.55 mechanical horsepower and 97.89 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 9.38 seconds to deliver, which is a floor rather than a real figure because it ignores drag and traction limits.
The result sits 1.554 hp past 95 hp, so if you need a round figure to quote, 95 hp is the honest nearest one. Plenty of people do this in their head: multiply by 1.3 instead of using the exact factor 1.34102209. At 72 that shortcut gives 93.6 horsepower, off by 2.954 horsepower or about 3.06%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.

How it works, step by step
- Start with 72 kilowatts.
- Scale it by 1.34102209 — that is how many horsepower fit in a single kilowatt.
- That gives 96.5535904508 horsepower.
- Going the other way, divide rather than multiply — 96.55359045 hp ÷ 1.34102209 brings you back to 72 kW.
