| 50 L/100km | 5.6496 mpg (UK) |
| 100 L/100km | 2.8248 mpg (UK) |
| 1,000 L/100km | 0.282481 mpg (UK) |
Formula
mpg(UK) = 282.4811 ÷ L/100km
Fuel economy can be expressed as distance per unit fuel (mpg, km/L, higher is better) or fuel per unit distance (L/100km, lower is better). They convert via inverse: mpg(US) × L/100km = 235.2146.
About Liters per 100 kilometers and Miles per gallon (UK)
Liters per 100 kilometers (L/100km): Standard fuel economy unit in metric countries; a measurement of fuel consumed per fixed distance (lower numbers are better). Common uses: EU and most non-US vehicle fuel economy ratings, fleet management, and shipping fuel-burn calculations.
Miles per gallon (UK) (mpg (UK)): Distance per UK imperial gallon (4.546 L, about 20% larger than the US gallon); the UK historically uses the imperial gallon, so UK mpg numbers look higher than US numbers for the same car. Common uses: UK vehicle specifications, UK car reviews, and historical British data.
How the conversion works
Fuel economy can be expressed as distance per unit fuel (mpg, km/L, higher is better) or fuel per unit distance (L/100km, lower is better). They convert via inverse: mpg(US) × L/100km = 235.2146.
The exact relationship is mpg(UK) = 282.4811 ÷ L/100km, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
