MPG Calculator
Work out fuel economy from distance and fuel used. Gives US MPG, UK MPG, L/100 km and km per litre; 300 miles on 10 gallons is 30 MPG.
Fuel Consumption Calculator
Work out fuel consumption from distance driven and fuel used. Shows L/100 km, km/L, US mpg and UK mpg; 300 miles on 10 US gallons is 7.84 L/100 km.
Trip Fuel Cost Calculator
Work out the fuel cost of a drive from distance, mpg or L/100 km and pump price, with a round-trip option and the cost split per passenger.
Fuel Economy Calculator
Turn distance driven and fuel used into L/100 km, km/L, US mpg and imperial mpg at once; 300 miles on 10 gallons reads as 30 mpg or 7.84 L/100 km.
Fuel Cost Calculator
Work out what a drive costs in fuel from distance, fuel economy and pump price. 300 miles at 30 mpg and $3.50 a gallon comes to $35.00.
Horsepower Calculator
Work out engine horsepower from torque and rpm, or estimate wheel horsepower from quarter-mile ET or trap speed and race weight. Shows kW and PS too.
Horsepower to Torque
Convert engine horsepower, kW or PS at a given rpm into torque in lb-ft and N·m using T = hp × 5252 ÷ rpm, with the working shown line by line.
HP Calculator
Work out engine horsepower from torque and rpm (hp = torque × rpm ÷ 5252), or estimate it from quarter-mile time or trap speed and race weight.
Torque Calculator
Convert engine power and rpm into torque in lb-ft, N·m and kgf·m. Accepts hp, kW or PS and shows the 5252 rpm working step by step.
Torque to Horsepower
Convert engine torque and rpm to horsepower, kilowatts and metric PS. Works in lb-ft or N·m; 300 lb-ft at 5,252 rpm equals exactly 300 hp.
Car Depreciation Calculator
Estimate what a car will be worth after 1 to 30 years from its price and a yearly loss in value, with the money lost each year shown in a table.
Auto Depreciation Calculator
Estimate what a car is worth after a number of years from its purchase price and a yearly percentage loss, with a year-by-year value table.
Kilometers per Liter Calculator
Divide kilometres driven by litres used to get km/L, then see the same economy as L/100 km, US mpg and UK mpg using exact gallon and mile definitions.
Speed Rating Chart
Look up a tire speed symbol from L to Y and see its maximum speed in km/h and mph, e.g. H = 210 km/h (130 mph), plus your headroom at cruising speed.
Miles per Gallon Calculator
Divide miles driven by gallons used to get US MPG, then see litres per 100 km, km per litre, imperial MPG and the fuel cost per mile at your pump price.
