When you need to convert miles per Imperial gallon to kilometers per liter
- 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 = 0.354006 kilometers per liter, the answer should be smaller 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.
- Kilometer per liter (km/L): Distance travelled per liter of fuel. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
