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.
