How the Fuel Economy Converter Works
Simply enter the fuel efficiency value in the original unit, select the unit you want to convert to, and the tool instantly provides the corresponding value. The calculator uses precise conversion formulas:
- MPG (US) to L/100km → 235.215 ÷ MPG
- MPG (UK) to L/100km → 282.481 ÷ MPG
- km/L to MPG (US) → km/L × 2.35215
- L/100km to km/L → 100 ÷ L/100km
Supported Units
- MPG (US): Miles per gallon (US standard)
- MPG (UK): Miles per gallon (Imperial)
- km/L: Kilometers driven per liter of fuel
- L/100km: Liters consumed per 100 kilometers
