Common Converters
Fuel Consumption Converter
Convert between kilometers per liter, miles per gallon (US and UK) and liters per 100 km. Note that L/100km is an inverse measure — a lower value is better — so conversion is reciprocal rather than proportional.

All supported units — fuel consumption
| Unit | Symbol | To kilometer/liter (km/L) | From kilometer/liter (km/L) |
|---|---|---|---|
| Kilometer/liter | km/L | 1 km/L = 1 km/L | 1 km/L = 1 km/L |
| Meter/liter | m/L | 1 m/L = 0.001 km/L | 1 km/L = 1,000 m/L |
| Mile/gallon (US) | mpg (US) | 1 mpg (US) = 0.42514371 km/L | 1 km/L = 2.35214583 mpg (US) |
| Mile/gallon (UK) | mpg (UK) | 1 mpg (UK) = 0.35400619 km/L | 1 km/L = 2.82480936 mpg (UK) |
| Liter/100 km | L/100km | inverse measure: km/L = 100.0 ÷ value | |
| Gallon (US)/100 mile | gal/100mi | inverse measure: km/L = 62.1371192237 ÷ value | |

Frequently asked questions
What units does this fuel consumption converter support?
It supports 6 units: Kilometer/liter (km/L), Meter/liter (m/L), Mile/gallon (US) (mpg (US)), Mile/gallon (UK) (mpg (UK)), Liter/100 km (L/100km), Gallon (US)/100 mile (gal/100mi).
What is the base unit of fuel consumption?
The SI reference unit is the kilometer/liter (km/L). Every conversion is computed by converting the input to the base unit, then from the base unit to the target unit, so chained precision is preserved.
Is this converter accurate?
Yes. Conversion factors use exact legal definitions where they exist (for example 1 in = 25.4 mm exactly) and CODATA/ISO constants otherwise. Results are shown to up to 10 significant figures.
