Fuel Consumption Converter
Car fuel economy both ways: L/100 km, km/L, and US or UK miles per gallon. Higher mpg means fewer L/100 km, so these use formulas instead of a simple multiplier.
That is below absolute zero (−273.15 °C), which isn’t physically possible.
1 mpg = 235.2145833 L/100 km
Formula: L/100 km = 235.215 ÷ mpg (US)

How to convert fuel consumption units
Car fuel economy both ways: L/100 km, km/L, and US or UK miles per gallon. Higher mpg means fewer L/100 km, so these use formulas instead of a simple multiplier. Some of these units are linked by a formula rather than a single multiplier, so the converter shows the formula it used with each answer.
Miles per gallon (US) to liters per 100 km (mpg to L/100 km)
Use the formula L/100 km = 235.215 ÷ mpg (US). 1 mile per gallon (US) = 235.2146 liters per 100 km.
| mpg | L/100 km |
|---|---|
| 4 mpg | 58.80365 L/100 km |
| 5 mpg | 47.04292 L/100 km |
| 6 mpg | 39.20243 L/100 km |
| 8 mpg | 29.40182 L/100 km |
| 10 mpg | 23.52146 L/100 km |
| 12 mpg | 19.60122 L/100 km |
| 15 mpg | 15.68097 L/100 km |
Liters per 100 km to miles per gallon (US) (L/100 km to mpg)
Use the formula mpg (US) = 235.215 ÷ L/100 km. 1 liter per 100 km = 235.2146 miles per gallon (US).
| L/100 km | mpg |
|---|---|
| 4 L/100 km | 58.80365 mpg |
| 5 L/100 km | 47.04292 mpg |
| 6 L/100 km | 39.20243 mpg |
| 8 L/100 km | 29.40182 mpg |
| 10 L/100 km | 23.52146 mpg |
| 12 L/100 km | 19.60122 mpg |
| 15 L/100 km | 15.68097 mpg |
Kilometers per liter to liters per 100 km (km/L to L/100 km)
Use the formula L/100 km = 100 ÷ km/L. 1 kilometer per liter = 100 liters per 100 km.
Liters per 100 km to kilometers per liter (L/100 km to km/L)
Use the formula km/L = 100 ÷ L/100 km. 1 liter per 100 km = 100 kilometers per liter.
