Fuel Economy Calculator
Free fuel economy calculator. Compute US MPG, L/100 km, and km/L from distance and fuel used on one tank.

About Fuel Economy Calculator
Informational only, not professional advice. Report an error.
Real-world economy beats brochure numbers when you divide distance by fuel used on one segment. This page reports L/100 km, km/L, and US MPG together for cross-border comparisons.
Metric mode expects kilometers and liters. Imperial mode expects miles and US gallons. All conversions use standard factors, not live telemetry.
Log multiple tanks in fuel-consumption-log-calculator when you want segment averages instead of one trip.

Common mistakes and fixes
Pasting API keys or secrets, tokens, or personal data into any browser tool.
Fix: Use redacted samples in development. Client-side processing still leaves data in browser memory and history.
Mixing date-only and datetime fields when the UI expects calendar dates.
Fix: Match the input style shown on the tool. Date-only mode counts calendar days, not clock times.
Picking the wrong unit category (weight versus volume, miles versus km).
Fix: Confirm unit labels on the tool match the values you entered before you copy the result.
