MPG & L/100km Converter
Convert fuel efficiency between Miles Per Gallon (UK MPG) and Litres per 100 Kilometers (L/100km).
Conversion Formulas Used:
From MPG to L/100km:
L/100km = (100 * 4.54609) / (MPG * 1.60934)
L/100km ≈ 282.48 / MPG
From L/100km to MPG:
MPG = (100 * 4.54609) / (L/100km * 1.60934)
MPG ≈ 282.48 / L/100km
Note: Uses UK Gallon (4.54609 litres) and standard mile (1.60934 kilometers).
