The MPG to l/100km UK converter below will help you to quickly calculate and convert miles per gallon (UK) to litres per 100 km.

All you have to do is input the MPG you want to convert to l/100km, and the calculator will give you an automatic conversion.

How to convert MPG to L100km

To convert MPG (miles per gallon) to L/100km (litres per 100 kilometres), you can use the following formula:

L/100km = 282.481 ÷ MPG

This means you take the value of 282.481 and divide it by the MPG value. For example, if a car achieves 40 MPG, the calculation would be:

L/100km = 282.481 ÷ 40 = 7.062 L/100km

MPG vs L100km

MPG and L/100km are two different ways of measuring fuel efficiency, and they are essentially inverse to each other.

MPG, or miles per gallon, measures how far a vehicle can travel using one gallon of fuel. Higher MPG means better fuel efficiency.

On the other hand, L/100km, or litres per 100 kilometres, measures how much fuel a vehicle uses to travel 100 kilometres. Lower L/100km values indicate better fuel efficiency.
