Fuel Cost Per Kilometre Calculator

Works out how much fuel costs you for every kilometre driven, from the fuel price and your vehicle’s consumption in litres per 100 km. It turns abstract fuel-economy figures into a real per-kilometre cost.

Horsepower from Torque Calculator

Calculate horsepower from torque (in lb-ft) and engine RPM using the classic HP = (torque × RPM) / 5252 formula. Use it to convert between dyno-measured torque curves and the more familiar horsepower figures that car spec sheets quote.
