MPG: 0.00

Kilometers Per Liter: 0.00

Calculation Formula

MPG = Miles Driven ÷ Gallons Used

Where:
MPG = Miles Per Gallon (fuel efficiency)
Miles Driven = Total distance traveled in miles
Gallons Used = Total fuel consumed in gallons

Miles Per Gallon Calculator Usage Guide

Learn how to use the Miles Per Gallon Calculator and understand fuel efficiency measurements

How to Use This Calculator

  1. Enter the total number of miles your vehicle has traveled
  2. Enter the total number of gallons of fuel that were consumed during that period
  3. Click the "Calculate" button to determine your vehicle's MPG
  4. The calculator will also display results in kilometers per liter (km/l)

Understanding Miles Per Gallon (MPG)

Miles Per Gallon (MPG) is a measure of a vehicle's fuel efficiency. It indicates how many miles a vehicle can travel per one gallon of fuel. Higher MPG values indicate better fuel efficiency (more miles per gallon).

Conversion Formulas

This calculator converts between US gallons to liters (1 gallon = 3.78541 liters) and miles to kilometers (1 mile = 1.60934 kilometers). The results are provided in both US customary units (MPG) and metric units (km/l).

Example Usage

If you drove 300 miles and used 10 gallons of fuel, your vehicle's MPG would be:
MPG = 300 miles ÷ 10 gallons = 30 MPG
