83 kilowatts is 111.3048334 hp. The exact arithmetic is 83 × 1.34102209 = 111.304833436 horsepower, using the defined factor rather than a rounded one, so this matches what a calibrated instrument would give you.
83 kW is 111.3 mechanical horsepower and 112.8 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 8.13 seconds to deliver, which is a floor rather than a real figure because it ignores drag and traction limits.
The result sits 1.305 hp past 110 hp, so if you need a round figure to quote, 110 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 83 that shortcut gives 107.9 horsepower, off by 3.405 horsepower or about 3.06%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.

111.3048334 hp- The converted result
How it works, step by step
- Start with 83 kilowatts.
- Apply the defined factor: one kilowatt is 1.34102209 horsepower, so multiply by that.
- That gives 111.304833436 horsepower.
- Going the other way, divide rather than multiply — 111.3048334 hp ÷ 1.34102209 brings you back to 83 kW.
