How to convert 46 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 ÷ 46 = 5.11 L/100 km

UK: 282.481 ÷ 46 = 6.14 L/100 km

For kilometres per litre, multiply instead: US MPG × 0.4251 = km/L, so 46 US MPG = 19.56 km/L. For UK MPG use × 0.3540, so 46 UK MPG = 16.28 km/L.

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