Miles per imperial gallon to Litres per 100 km
1 mile per imperial gallon = 282.48 litres per 100 km · 1 L/100 km = 282.48 mpg (UK)
1 mile per imperial gallon = 282.48 litres per 100 km
How it’s calculated
L/100 km = 282.4809363 ÷ mpg (UK)
- These units are inversely related (one measures amount per distance, the other distance per amount), so divide 282.4809363 by the value.
- Doubling one halves the other. A value of zero has no finite equivalent.
- 1 mpg (UK) = 282.4809363 L/100 km · 1 L/100 km = 282.4809363 mpg (UK)

These units are inversely related
One unit measures “per distance” and the other “per volume” or “per time”, so the conversion divides instead of multiplying. Go through km/L. Source: Derived from exact length, volume and time definitions (NIST SP 811 / Handbook 44).
Convert to km/L
Convert km/L to L/100 km
L/100 km = 100 ÷ km/L
Round the answer
Rounded to 5 significant figures.
Answer: 282.48 L/100 km
