What is MPG Calculator?
The MPG calculator is essential for calculating your vehicle’s Mile per Gallon. This calculator also measures fuel consumption and mileage to optimize a car’s fuel cost. The metric used in this calculator is the Imperial Gallon which is 1.2 times higher than the US Gallon. For this reason, the value of UK MPG is always higher than US MPG for the same vehicle.
In this article, I have explained several aspects of How the calculator Functions and the benefits of the calculator. Additionally, I have also explained how you can calculate Miles per gallon easily and fast.
A step-by-step guide to using our MPG calculator
Our calculator is simple to use. Follow the instructions below and you are good to go!
- Input total miles travelled: Enter the total distance (in miles) you covered after the recent refuelling.
- Enter the amount of gallons used: Enter the amount of fuel (in gallons) you added in the recent refuelling time.
- Click the “Calculate” button: Click the “calculate” button to estimate your car’s Miles per gallon.
How to calculate Miles per Gallon (MPG) for the UK cars
To calculate MPG in the UK, the most common distance and volume metrics we use are Miles and Gallon respectively.
So, the formula will be, MPG = Distance travelled / litres * 0.219969
For example, Distance = 300 miles
Fuel used = 60 litres
MPG = 300 / (60 * 0.219969) = 22.73
So, the fuel efficiency of a car = 22.73

Importance of using MPG calculator
- Financial benefits: to save petrol or diesel costs, you need to improve your vehicle’s mileage. Accurate knowledge of how much petrol or diesel you need will improve fuel economy. Moreover, it will help you plan your monthly budget to avoid unnecessary expenses.
- Environmental impacts: A fuel-efficient car whether a hybrid or an Electric helps reduce carbon emissions and carbon footprints. As a result, the impacts on the climate have significantly become less, leading to a cleaner and greener environment.
Tips to improve your vehicle’s mileage
- Maintain tire pressure: choosing the right tire is key to reducing fuel consumption. The under-inflated tire is the best option because its rolling resistance is comparatively lower than that of other tires. This type of tire reduces gas mileage by 0.3% per PSI. Moreover, you must align the tire with the wheel properly to avoid any kind of damage to the tire.
- Reduce excess weight: if your car is heavy, it needs more fuel to run. Lighter cars are the best for fuel efficiency. To achieve that, you need to remove unnecessary loads from your car and keep your car in good shape.
- Avoid reckless driving: frequent acceleration and sudden braking need more fuel. Even if you drive a long and rural highway, your vehicle consumes a high amount of fuel. So, cruise control can be a great solution to this. Besides, you must keep your at an optimal speed of 55km/hr to improve fuel efficiency.
- Proper air conditioning: in hot climates, unnecessary air conditioning usage causes havoc on fuel economy. If you keep your car’s AC while the car is in idle state, your car’s fuel efficiency is reduced by 25%. So, use an AC system when your car is moving.
- Drive a fuel-efficient hybrid or EV: if you are an owner of a hybrid or electric vehicle, you can reduce your fuel costs and carbon emissions. Before, choosing the right vehicle, you must understand the detailed comparison of these vehicles.
What is good MPG for UK cars
A good MPG depends on multiple factors including type of car and driving habit. Usually, a good MPG lies between 50 and 70. Any MPG that is below 30 is considered bad MPG.
| Car Type | MPG |
| City cars and small hatchback cars | 60-70 |
| Family car and sedan | 50-60 |
| Large SUVs and Luxury cars | 50 |
| Executive cars | 50 |
| Hybrid and Plug-in hybrid cars | 70 |
UK fuel prices and how they affect MPG in 2024
Several factors drive fuel cost fluctuations in the United Kingdom. These factors include crude oil prices in the international market, exchange rates, and taxes. This fluctuation impacts the cost of driving. The gradual changes in fuel (petrol + diesel) prices in 2024 have been shown below:
As petrol and diesel prices change frequently in the UK, it is necessary to know MPG to reduce fuel costs. To do so, you must change the way you drive. The safest driving habits include leveraging cruise control and avoiding coasting or drifting. If you drive a car with better mileage, the average combined MPG will increase. The average MPG in the United Kingdom is considered 40.
Tools and converters related to Miles per Gallon calculator
- MPG to MPL converter: while the MPG metric is widely used in the UK, some prefer Miles per litre (MPL). You can check the MPG to MPL converter to estimate your car’s mileage per litre.
- MPG to L/100km: Various European countries use different measurement systems. If you are driving a car outside the UK, you can compare your car’s fuel consumption with that of other cars on a 100km base.
- Fuel Cost Calculator: The fuel cost calculator is an importation tool in fuel economy. You can use this calculator to estimate fuel costs for a journey.
- Litre to gallon converter: a Litre to gallon converter is a useful volume conversion tool. This tool will be handy in those countries where litre is more popular than gallons.
Final words
In conclusion, by Knowing your car’s fuel efficiency using our calculator, you can significantly save fuel costs and environmental impact. If you are a UK driver, our calculator will help you estimate fuel consumption to keep fuel economy afloat.
