How it works

Two steps, no account

1

Pick your units

Distance-per-volume (mpg, km/L) or volume-per-distance (L/100km, gal/mi) — both directions are covered.

2

Enter a value

The result updates instantly as you type, or as soon as you change either unit.

FAQ

Common questions

Is my data sent anywhere?
No. The conversion runs entirely in your browser — nothing is transmitted, logged, or stored.
Why are US and UK gallons listed separately?
A US gallon (3.785 L) and a UK/imperial gallon (4.546 L) are different sizes, so mpg figures quoted in each aren't directly comparable — mixing them up is a common source of confusion when comparing fuel economy across regions.
