Put 59 kilowatts into the exact factor of 1.34102209 and you get 79.12030329 hp. Written out: 59 × 1.34102209 = 79.1203032861 horsepower, with no rounding applied until the final display.
59 kW is 79.12 mechanical horsepower and 80.22 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 11.4 seconds to deliver, which is a floor rather than a real figure because it ignores drag and traction limits.
The result sits 0.8797 hp short of 80 hp, so if you need a round figure to quote, 80 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 59 that shortcut gives 76.7 horsepower, off by 2.42 horsepower or about 3.06%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
