### What is MPG?

MPG stands for "miles per gallon", and is a unit of measurement used to measure the fuel efficiency of a car. The higher the value, the more efficient your car is. MPG is typically used in the United States, Canada, and the United Kingdom to measure how much fuel a vehicle consumes.

### What is KM/L?

KM/L stands for "kilometers per litre", and is an alternative unit of measurement used to measure the fuel efficiency of a car. The higher the value, the more efficient your car is.

### How to Calculate the Metric Conversion

To calculate KM/L simply divide the number of kilometers traveled by the number of litres used for fuel.

### How to Convert MPG to KM/L?

Miles per gallon does not use the metric system, so it needs to be converted before making any calculations. First, take the number of miles from your mpg metric and convert that to km by multiplying by 1.609. For example, a car that does 30 mpg would become 48.27 km per gallon. Next, we need to convert the gallon part of mpg to litres. There are 4.546 litres in a UK gallon, so we divide our 48 km per gallon by 4.546 to arrive at 10.62 KM/L.
