Litres per 100 km
- Miles per US gallon
- 33.6 mpg
- Miles per UK gallon
- 40.35 mpg
- Kilometres per litre
- 14.29 km/L
How it is calculated
- US gallon = 3.785411784 L; UK (imperial) gallon = 4.54609 L; mile = 1.609344 km.
- L/100 km = 100 ÷ (km/L).
- US MPG ≈ 235.215 ÷ (L/100 km); UK MPG ≈ 282.481 ÷ (L/100 km).
- After a trip: km/L = distance ÷ fuel.
Example
7 L/100 km = 33.6 US MPG = 40.4 UK MPG = 14.3 km/L.
Good to know
- The US gallon is smaller than the UK gallon: their MPG figures differ.
- In L/100 km, lower is better; in MPG and km/L, higher is better.
- Real fuel use depends on driving, load and weather.
Sources
- Legal values of the US gallon (NIST Handbook 44) and the imperial gallon (Weights and Measures Act 1985)
