This MPG to l/100km converter is programmed to quickly convert UK miles per gallon to litres per 100 kilometres and litres per 100km to miles per gallon.
To begin, input the MPG figure you need to convert to l/100km into the first calculator or input the l/100km figure you need to convert to MPG into the second calculator to get an instant conversion.
What is l/100km?
L/100km stands for “litres per 100 kilometres” and is a metric used to measure fuel efficiency. It is the amount of fuel (in litres) consumed per 100 km travelled. Generally, the lower the l/100km value, the more fuel-efficient a vehicle is considered to be.
How to convert UK MPG to l/100km
To convert MPG to l/100km, all you have to do is divide 282.481 by the MPG figure. This will give you the conversion rate in l/100km. For example, if a car gets 40 mpg, then its fuel efficiency would be 7.06 l/100km (282.481 ÷ 40 = 7.06).
What’s a good l/100km figure?
The ideal l/100km figure varies depending on the vehicle, how it’s used and the driving environment. Generally speaking, a good l/100km figure for small to medium-sized cars in the UK is around 6-7 in city driving, 4-5 in motorway driving, and 5-6 combined.
Why you should calculate your l/100km
Here are a few reasons why you should calculate your vehicle’s l/100km.
- It can help you to estimate the cost of fuel for long journeys or daily commutes.
- It can help you to track and improve your fuel efficiency.
- It can help identify any issues with your car’s efficiency that may need to be addressed.
- It can provide insight into how different driving styles or conditions affect fuel consumption, allowing you to make adjustments accordingly.
