FAQ
- Does this use US or imperial gallons?
- US gallons. A US gallon is about 3.785 liters. If your mpg figure is imperial, it will read a little lower in L/100km than the true value.
- What is the formula?
- Liters per 100 km equals 235.214583 divided by the mpg value, because the two units are inverses of each other.
- Is a higher or lower L/100km better?
- Lower is better. L/100km counts fuel used over a fixed distance, so a smaller number means the car is more efficient.
