Formula: L/100km = 235.21 ÷ MPG (US)
Reverse: Reverse: MPG (US) = 235.21 ÷ L/100km
Example (average car): 29.4 MPG (US) = 8 L/100km
⚠ L/100km is inverse — lower = better fuel economy, higher = worse.

Divide 235.21 by MPG value.
30 MPG US = 7.84 L/100km. 40 MPG US = 5.88 L/100km. 50 MPG US = 4.70 L/100km.
MPG (US) = 235.21 ÷ L/100km.
Compares fuel economy across international vehicle specs — converting between MPG (US), MPG (UK), km/L, and L/100km.
Calculates fuel costs and sets efficiency targets using L/100km (Europe/Australia) or MPG (US/UK).
Converts between regional fuel economy standards when reviewing international vehicle launches.
Converts fuel economy specs of rental vehicles between familiar and local units.
Converts fuel efficiency data to calculate CO₂ emissions across vehicle fleets in different units.
Validates fuel efficiency test results across EPA (MPG US), WLTP (L/100km), and JC08 (km/L) cycles.
Miles per gallon — US (MPG US) uses the US gallon of 3.785 liters. It is the mandatory fuel economy rating in the United States and is published by the EPA for all new vehicles sold in the US. The US gallon is about 17% smaller than the Imperial gallon.
EPA fuel economy ratings: combined city/highway. A typical American sedan achieves 28–35 MPG; a large pickup truck 16–22 MPG; Toyota Prius hybrid 50–57 MPG; the Tesla Model 3 is rated at 132 MPGe (miles per gallon equivalent). The CAFE standard requires ~49 MPG fleet average by 2026.
Interesting fact: The US MPG standard was introduced in response to the 1973 Arab oil embargo. The EPA fuel economy label on new vehicles has been redesigned multiple times, most recently in 2013, and now also shows MPGe (miles per gallon equivalent) for electric and plug-in hybrid vehicles.
Liters per 100 kilometers (L/100km) is the standard fuel consumption unit in most of Europe, Australia, Canada, China, and many other countries. Unlike other units, a LOWER L/100km value means BETTER fuel economy — it measures consumption, not efficiency.
EU emissions regulations are linked to L/100km figures. A typical European compact car achieves 5–7 L/100km; an efficient diesel 4–5 L/100km; a large SUV 9–12 L/100km. The EU 2025 fleet-average CO₂ target (95 g/km) corresponds roughly to 4.1 L/100km for petrol.
Interesting fact: L/100km and km/L are mathematically inverse: L/100km = 100 ÷ km/L. This means improvements aren't linear — going from 20 to 10 L/100km doubles efficiency, but going from 10 to 5 L/100km doubles it again. Small improvements at high consumption have disproportionately large real-world impact.
Fuel efficiency is measured differently across regions: km/L (Japan, India), L/100km (Europe, Australia, Canada), MPG US (USA), MPG UK (Britain). Converting between them is essential for international vehicle comparisons. Note: L/100km uses an inverse relationship — lower = better, and you cannot simply multiply to convert.
Formula: L/100km = 235.21 ÷ MPG (US). Reverse: MPG (US) = 235.21 ÷ L/100km.
All conversions use exact gallon definitions: US gallon = 3.785411784 L; Imperial gallon = 4.54609 L.
