Practical use cases and industry applications
Understanding Fuel Economy
Convert MPG (US/UK) to L/100km and vice versa. Within unit conversion tools, fuel economy belongs to the weight, temperature & physics cluster, where it shares terminology and assumptions with closely related tools.
Learning how fuel economy is calculated
Fuel economy conversions use the standard gallon and mile definitions for each region. Working through the variables one at a time — — makes the result reproducible by hand and easier to sanity-check.
Using fuel economy to make a decision
Because outputs depend on the assumptions you enter, run more than one scenario before committing to a figure.
How fuel economy compares with related measures
kilogram, kelvin, pascal, joule all describe adjacent aspects of weight, temperature & physics. Comparing this calculator's output against those measures — using the related tools listed on this page — prevents a single metric from being read in isolation.
