The short answer: 82 kilowatts comes to 109.9638113 hp. That is 82 multiplied by 1.34102209, the factor fixed by definition, carried to full precision before anything is rounded for display.
82 kW is 110 mechanical horsepower and 111.5 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 8.23 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 110 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 82 that shortcut gives 106.6 horsepower, off by 3.364 horsepower or about 3.06%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
The formula
82 kW- The quantity being converted
1.34102209- Exact horsepower in one kilowatt
109.9638113 hp- The converted result
How it works, step by step
- Take the kilowatt value, 82.
- Apply the defined factor: one kilowatt is 1.34102209 horsepower, so multiply by that.
- Result: 109.963811347 horsepower.
- Going the other way, divide rather than multiply — 109.9638113 hp ÷ 1.34102209 brings you back to 82 kW.
