US miles per gallon to liters per 100 kilometers
Fuel economy uses a reciprocal conversion: a higher miles-per-gallon value corresponds to a lower liters-per-100-kilometers value. One US mpg is about 235.214583 L/100 km when expressed as the reciprocal.
| US mpg | L/100 km |
|---|---|
| 10 | 23.521 |
| 20 | 11.761 |
| 25 | 9.409 |
| 30 | 7.840 |
| 40 | 5.881 |
| 50 | 4.704 |
US and Imperial gallons are different sizes, so US mpg and Imperial mpg produce different results.
How to convert fuel economy
Choose the starting and destination units. The converter accounts for the inverse relationship between mpg and L/100 km, so you do not need to invert the value yourself.
