How to convert 25 MPG to L/100km and km/L

Divide a fixed constant by the MPG figure. The constant is the litres in one gallon, divided by the kilometres in one mile, multiplied by 100.

US: 235.215 ÷ 25 = 9.41 L/100 km

UK: 282.481 ÷ 25 = 11.30 L/100 km

For kilometres per litre, multiply instead: US MPG × 0.4251 = km/L, so 25 US MPG = 10.63 km/L. For UK MPG use × 0.3540, so 25 UK MPG = 8.85 km/L.

Based on 1 mile = 1.609344 km, 1 US gallon = 3.785411784 L and 1 imperial gallon = 4.54609 L (NIST definitions).
