Fuel Economy Converters
Compare fuel consumption and efficiency units with direct mirror pages and a shared liters-per-100-kilometers normalization basis. This hub keeps metric, US, and UK fuel-economy standards aligned.
Scope & Verification
This hub groups related converter families so you can move from the category level to exact routes with one clear basis per page.
- Families are split so exact-factor, profile-based, density-based, and estimate-style pages do not collapse into one generic answer.
- Leaf pages keep calculator, common values, FAQ, and reverse routes aligned to the same assumption.
- Methodology and verification pages document how those assumptions are chosen and checked.
Explanation
Fuel economy can be expressed either as consumption (liters per distance) or efficiency (distance per liter or gallon). This hub keeps each direction as a dedicated page and preserves reversible formulas through a shared liters-per-100-kilometers reference, so metric, US, and UK standards stay aligned across calculator output, common values, FAQs, and mirror pages.
Fuel Economy converters are grouped into directional families so each leaf keeps one stable conversion model.

Frequently Asked Questions
Why are mpg and L/100km inversely related?
mpg increases with better efficiency, while L/100km decreases for the same improvement because it measures fuel consumed per distance.
Is UK mpg the same as US mpg?
No. UK gallons are larger than US gallons, so mpg (UK) values are higher for the same vehicle performance.
Do all pages have mirror routes?
Yes. Every direction has a dedicated reverse page reachable with the switch button.
