Kilometers To Miles Per Gallon Calculator

Convert vehicle fuel efficiency from kilometers per liter (km/L) to miles per gallon (mpg) to compare with US fuel economy standards

Input Parameters

Enter the vehicle's fuel efficiency in kilometers per liter

Calculation Results

Calculation Formula

mpg = (km/L × 1.60934 × 3.78541)

Where:
km/L = Kilometers per liter fuel efficiency
1.60934 = Kilometers in one mile
3.78541 = Liters in one gallon

The equivalent fuel efficiency in miles per gallon

Kilometers To Miles Per Gallon Calculator Calculator Usage Guide

Learn how to use the Kilometers To Miles Per Gallon Calculator and understand fuel efficiency conversions

How to Use This Calculator

  1. Enter the vehicle's fuel efficiency in kilometers per liter (km/L) in the first input field. This is typically found on European vehicle specifications.
  2. Click the "Calculate" button to convert the value to miles per gallon (mpg).
  3. The result will be displayed in the second input field showing the equivalent fuel efficiency in mpg.

Understanding Fuel Efficiency Conversions

Fuel efficiency is often measured differently across regions. In Europe, fuel efficiency is typically measured in kilometers per liter (km/L), while in the United States, it's measured in miles per gallon (mpg).

The conversion formula used in this calculator is:

mpg = (km/L × 1.60934 × 3.78541)

Where:

  • 1.60934 is the conversion factor from kilometers to miles
  • 3.78541 is the conversion factor from liters to gallons

For example, if a car has a fuel efficiency of 12 km/L, the equivalent in mpg would be:

12 × 1.60934 × 3.78541 = 47.82 mpg

Why Convert Fuel Efficiency?

Converting between different fuel efficiency measurements can help you:

  • Compare vehicles from different regions
  • Understand your vehicle's fuel consumption in familiar units
  • Make more informed decisions about fuel efficiency when purchasing a vehicle
