When you need to convert miles per Imperial gallon to liters per 100 kilometers

  • Comparing a car's efficiency between US MPG, Imperial MPG and litres per 100 km.
  • Estimating fuel cost for a trip in another country.

Common mistakes to avoid

  • Dividing when you should multiply. Because 1 mile per Imperial gallon = 282.481 liters per 100 kilometers, the answer should be larger than the number you started with.
  • Averaging fuel economy figures directly. MPG is an inverse measure, so the average of two MPG figures is not the fuel economy of the two trips combined.
  • Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.

How precise does the answer need to be?

Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.

How these units are defined

  • Mile per Imperial gallon (MPG (imp)): The UK fuel-economy rating: miles per Imperial gallon (about 20% larger than US MPG). The accepted value is a measured or conventional figure rather than an exact definition, so the factor shown is rounded.
  • Liter per 100 kilometers (L/100km): Fuel consumed per 100 km — the standard rating in Australia, New Zealand, Canada and Europe. Lower is better. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
