How to read this result

Three useful checks, kept deliberately short.

What this result includes

10 L/100 km is approximately 23.5215 US mpg.

A practical example

Convert 10 L/100 km to US mpg: Use L/100 km as the reference Β· Divide 235.214583 by 10 Β· Display US mpg.

Common input mistake

km/L and mpg are distance-per-fuel measures, so a higher number is better.

Formula and assumptions

km/L = 100 Γ· L/100 km; US mpg = 235.214583 Γ· L/100 km

L/100 km is a consumption measure, so a lower number is better.

Keep in mind: Real fuel use varies with traffic, load, weather, tyres and driving style.
