How it works
Every unit in this dimension is defined as a ratio to one base unit — the kilometer per liter. Converting is therefore two multiplications: into the base unit, then out of it.
L/100km = 235.215 ÷ mpg (US) · the two are reciprocals Miles per gallon and L/100 km run in opposite directions
MPG measures distance per fuel; L/100 km measures fuel per distance. They are reciprocals, so a higher MPG is better while a lower L/100 km is better, and going from 15 to 20 MPG saves far more fuel than going from 40 to 45.
Rounding
Results are rounded to 8 significant figures, adjustable with the slider above. Exact factors are used internally, so chaining conversions does not accumulate error.
Sources
Conversion factors follow NIST Special Publication 811 (Guide for the Use of the International System of Units) and the BIPM SI Brochure, 9th edition. Every factor is checked by an automated round-trip test on each build.
