How to Convert MPG to L/100km

This is a division, not multiplication (because MPG and L/100km are inversely related):

L/100km = 235.215 Γ· MPG

Example: 30 mpg (standard sedan)
= 235.215 Γ· 30 = 7.8 L/100km

Example: 50 mpg (hybrid)
= 235.215 Γ· 50 = 4.7 L/100km

Example: 15 mpg (pickup truck)
= 235.215 Γ· 15 = 15.7 L/100km

Key insight: MPG measures how far you go (higher = better), while L/100km measures how much fuel you use (lower = better). They move in opposite directions.

The MPG illusion: Going from 15β†’20 mpg saves more fuel than going from 35β†’50 mpg (for the same distance). L/100km makes fuel savings obvious: 15.7β†’11.8 = saves 3.9L vs 6.7β†’4.7 = saves 2.0L per 100km.

What Is Miles per Gallon (MPG)?

Miles per gallon (MPG) measures fuel efficiency β€” how far a vehicle travels on one US gallon (3.785 liters) of fuel. Higher MPG = better fuel economy. The US EPA rates every new car in MPG. US gas is sold by the gallon, so MPG directly tells Americans their cost per mile.

What Is L/100km?

Liters per 100 kilometers (L/100km) measures fuel consumption β€” how many liters a vehicle needs to travel 100 km. Lower = better. It's the global standard used in Europe, Canada, Australia, Japan, and most of the world. Fuel is sold by the liter internationally, so L/100km directly shows fuel cost per trip.
