About Fuel Economy Conversions
Fuel economy measurements use fundamentally different approaches across regions. The US expresses efficiency as miles per gallon (MPG) — higher is better — while most of Europe uses liters per 100 kilometers (L/100km) — lower is better. This inverse relationship makes mental conversions tricky: 30 MPG (US) equals about 7.84 L/100km, while 5 L/100km equals about 47 MPG. Additionally, US gallons and imperial gallons differ, so UK MPG figures are about 20% higher than US MPG for the same vehicle. Our converter handles all three standards with exact conversion factors.
| Unit Name | Symbol | Value | Formula |
|---|---|---|---|
| Kilometer per Liter | km/L | 1 | base unit |
| Liter per 100km | L/100km | 100 | divide 100 by value |
| Mile per Gallon (UK) | mpg (UK) | 2.82481 | multiply by 0.354006 |
| Mile per Gallon (US) | mpg | 2.35214 | multiply by 0.425144 |
