Converting 82 horsepower gives 61.14738947 kW. One multiplication does it — 82 × 0.7456998716 = 61.1473894697 kilowatts — and because the factor is defined rather than measured, that answer will not drift over time.
61.1474 kW is 82 mechanical horsepower and 83.14 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 11 seconds to deliver, which is a floor rather than a real figure because it ignores drag and traction limits.
The result sits 1.147 kW past 60 kW, so if you need a round figure to quote, 60 kW is the honest nearest one. Plenty of people do this in their head: divide by 1.3 instead of using the exact factor 0.7456998716. At 82 that shortcut gives 63.076923 kilowatts, off by 1.93 kilowatts or about 3.16%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
