Fuel Calculator: Gas Mileage1.2.2 - Google Play

How much will the drive cost, how much fuel will it burn, and how far will a tank take you? Fuel Calculator answers all three from numbers you already have: distance, fuel price and either your car's consumption or the liters you filled up. Results come in your units, with the decimals you choose, and any calculation can be saved as a trip.

Three tabs, one job each. Volume works out fuel consumed and trip cost from efficiency, distance and price. Efficiency turns the fuel you used and the distance you covered into your real fuel economy, shown in every unit at once, from L/100 km to MPG. Distance tells you how far a given amount of fuel will take you.

WHY YOU'LL LOVE FUEL CALCULATOR

• Volume tab: enter Fuel Efficiency, Distance and Fuel Price; get Fuel Consumed and Fuel Cost for the trip.
• Efficiency tab: enter Fuel Consumed, Distance and Fuel Price; get Fuel Efficiency converted into up to twelve units side by side, plus Fuel Cost.
• Distance tab: enter Fuel Efficiency, Fuel Consumed and Fuel Price; get the Distance that fuel covers and what it costs.
• Twelve efficiency units: L/100 km, L/10 km, L/km, L/mile, miles per US gallon, miles per UK gallon, miles per liter, km/L, km per US gallon, km per UK gallon, US gallons per 100 miles, UK gallons per 100 miles. Fuel price per liter, US gallon or UK gallon; distance in kilometers or miles.
• Displayed Units: hide the units you never use, so every picker and result list shows only yours.
• Decimals: choose 0 to 10 decimal places for results.
• Save Trip: name a calculation (up to 50 characters) and find it in Trips, newest first, with its inputs and results.
• Share Result: send any result as plain text, formatted with your decimals, from the calculator or from a saved trip.
• The calculator remembers your last entries and units, so a regular commute takes one tap.
• Useful Content: articles on cutting fuel consumption, keeping a car in shape, engine types and choosing or buying a car.
• Works offline, no account, light and dark themes, 73 languages.

HOW IT WORKS

1. Pick a tab: Volume, Efficiency or Distance.
2. Enter the three values, choosing the unit next to each field.
3. Tap Calculate; save the trip or share the result.

PERFECT FOR

• Road trips and holiday drives you want to budget before leaving.
• Commuters who want the real monthly cost of the drive to work.
• Anyone checking what a car actually does, in MPG or L/100 km, after a fill-up.
• Drivers who cross borders and units and want one calculator for all of them.

TIPS FROM THE ROAD

• Fill the tank, note the odometer, and at the next fill-up enter liters and distance in Efficiency: that is your true consumption, not the brochure figure.
• Comparing two cars? Run the same distance and price through Volume with each car's efficiency; the difference in Fuel Cost is what you save on every trip.
• Sharing a ride? Calculate Fuel Cost once, share it, and divide.

UNITS THAT MATCH YOUR REGION

Liters per 100 km in Europe, miles per gallon in the US and the UK (different gallons, and the app knows), kilometers per liter in Asia and Latin America. Mix them freely: a car rated in L/100 km, fuel priced per US gallon and a distance in miles still give one correct answer. Conversions use exact factors; your decimals setting applies everywhere.

YOUR DATA STAYS WITH YOU

Nothing is uploaded and no account is needed. Trips and settings live on your device, the calculator works without internet, and sharing happens only when you choose it.

Fuel calculator and gas calculator for petrol, diesel and any vehicle: work out trip cost and fuel cost, gas mileage in MPG, L/100 km or km/L (kml), the fuel a trip burns and the distance a tank covers, for every car and every commute, offline, in 73 languages.
