Unit definitions
What is a mile per imperial gallon?
Miles per imperial gallon is the fuel-economy measure used in the United Kingdom. The imperial gallon (4.546 liters) is about 20% larger than the US gallon, so the same car reads a higher mpg figure in UK units than in US units — a common source of confusion when comparing quoted economy.
What is a liter per 100 km?
Liters per 100 kilometers (L/100km) is the standard fuel-consumption measure across Europe and most of the world. It states how much fuel a vehicle burns to travel 100 km, so a lower number means a more efficient car — the opposite direction to miles-per-gallon.
Frequently asked questions
What is the formula to convert miles per imperial gallon to liters per 100 km?
L/100km = 282.48094 ÷ mpg (UK). For example, 20 mpg (UK) equals 14.124 L/100km.
Why isn't mile per imperial gallon to liter per 100 km a simple multiplication?
Because one unit measures fuel per distance and the other measures distance per fuel — they are reciprocals. Doubling the mile per imperial gallon value roughly halves the liter per 100 km value, so the conversion divides rather than multiplies.
Is this mile per imperial gallon to liter per 100 km converter free?
Yes — the converter is free, works offline once loaded, and computes instantly in your browser without sending your numbers to a server.
