# Motor Vehicle Fuel Consumption Unit Conversion Calculator

Convert between **European** (metric), **British** and **American** motor vehicle **fuel consumptio**n measures: **US MPG** : **Imperial MPG** : **Litres/100km**.

**Including** Fuel Consumption Calculator (below) - which takes the amount of gasoline (petrol), diesel or gas (LPG/methane) added and the distance you driven (with optional **fuel cost calculator** to show cost per mile or kilometer in US Dollars, British Pounds and Euros).

## Convert Your Fuel Consumption

This calculator **converts between** various measures of fuel consumption of motor vehicles:

**Litres per 100km** - the European standard.
**Miles per Imperial Gallon** - the UK standard (also used in Canada etc.).
**Miles per US Gallon** - the standard in the USA.

### Note

There are 1.200949857 US gallons to 1 Imperial (UK) gallon (US gallons are smaller). Therefore 20 miles per US gallon (less fuel) is more economical than 20 miles per imperial (UK) gallon (more fuel).

## Fuel Consumption Calculator

Use this too if you know your distance and amount of fuel (and optionally your spending) and want to work out the fuel consumption that you achieved.

The best way to use this tool is: (a) Top up your fuel tank and zero your trip meter. (b) Make a trip in your car. (c) Top up your tank again, recording the amount of fuel added and the distance shown on your trip meter.

## About

This converter and calculator can help your tailor your driving technique to ensure cost effective motoring. It works fine for cars and motorbikes as well as for other vehicles.

I initially created this page in 2006 to aid discussion of the fuel economy of my classic Range Rover on an online forum.
