Calculate fuel economy in multiple units and optionally determine cost per distance.
A Miles Per Gallon (MPG) Calculator is a tool designed to help you determine your vehicle's fuel efficiency. Whether you're calculating miles per gallon (MPG), liters per 100 kilometers (L/100 km), or kilometers per liter (km/L), this tool provides accurate results based on your inputs. It supports multiple units for distance (miles or kilometers) and fuel volume (liters, US gallons, or UK gallons).
Miles per gallon (MPG) is a measure of how far your vehicle can travel on one gallon of fuel. It is a crucial indicator of fuel efficiency. A higher miles per gallon value means your vehicle uses less fuel to cover the same distance, saving you money on fuel costs.
You'll commonly see this metric expressed as US MPG (used in the United States) or UK MPG (used in the United Kingdom), the difference being in the gallon measurement.
How many miles is 1 gallon of gas? The answer varies greatly depending on your car. Our calculator will help you understand the exact miles you can travel per gallon.
Fuel efficiency is a critical factor for drivers. Knowing your vehicle's MPG helps you:
To manually calculate miles per gallon, use the formula:
Example:
If you traveled 300 miles and used 10 gallons of fuel:
If you are interested to know how to calculate gallons per mile , simply divide the fuel consumed by the distance traveled. For how to calculate miles per gallon cost, you need the cost per liter or gallon and then, simply multiply the fuel used by the cost per liter or gallon, and further divide by the distance traveled. Our calculator handles all these calculations for you, allowing you to find the miles per gallon cost or the cost per distance.
Manually calculating miles per gallon can be cumbersome, which is why our calculator is designed to streamline the process
How Much is 40 MPG in Liters per 100 Kilometers?
To convert MPG to L/100 km, use:
For 40 MPG:
Example 1: Calculating Miles Per Gallon
Example 2: Calculating Fuel Cost Per Mile
Example 3: How Many Miles Can 1 Gallon of Gas Cover?
If your car has an efficiency of 25 MPG, 1 gallon of gas will allow you to travel:
1. Measure the distance you traveled. 2. Record the amount of fuel used. 3. Divide the distance by the fuel consumed.
An MPG of 20 is average for older vehicles or larger vehicles like trucks and SUVs. Modern compact cars and hybrids often exceed 30-40 MPG.
40 US MPG is approximately 5.88 liters per 100 kilometers, our calculator will handle this conversion for you.
The main units are miles per gallon (MPG), liters per 100 kilometers (L/100 km), and kilometers per liter (km/L).
Different countries have their own standards and unit systems, so you will find fuel efficiency being expressed differently, such as MPG in the USA and L/100km in Europe.
By maintaining your vehicle well, avoiding hard acceleration and braking, using cruise control on highways, and reducing the weight in your car.
Budgeting: Knowing your miles per gallon helps you estimate fuel costs for your regular trips and plan your budget effectively.
Cost Savings: Choosing a more fuel-efficient vehicle or improving your driving habits can significantly reduce fuel consumption and save you money over time.
Environmental Impact: Lower fuel consumption means reduced emissions, contributing to a cleaner environment.
Comparing vehicles: The mpg value helps you in comparing between different vehicles.
