Gallons per Mile Calculator
Calculate your vehicle’s fuel consumption in gallons per mile with our comprehensive calculator. Determine fuel efficiency and compare with different vehicle types and driving conditions.
Step 1: Vehicle Information
Understanding Fuel Consumption
Gallons per mile (GPM) measures fuel consumption, while miles per gallon (MPG) measures fuel efficiency. Lower GPM values indicate better fuel efficiency. Electric vehicles show equivalent energy consumption.
Step 2: Driving Conditions
About Driving Style
Aggressive driving with rapid acceleration and braking can increase fuel consumption by 15-30% at highway speeds and 10-40% in stop-and-go traffic. Smooth, anticipatory driving maximizes fuel efficiency.

Fuel Consumption Breakdown
Fuel Consumption Formulas
Gallons per Mile (GPM) = Fuel Used / Distance
Miles per Gallon (MPG) = Distance / Fuel Used
Liters per 100km = (Fuel Used in Liters / Distance in km) × 100
To calculate fuel consumption: Divide fuel used by distance traveled for GPM, or distance by fuel used for MPG. For metric units, convert to liters and kilometers first.
