The Free Online Fuel Consumption Converter helps you convert one measuring unit of fuel consumption into another measuring unit.

You can convert between gallons (UK)/100 miles, gallons (US)/100 miles, kilometers/liter (km/l), liters/100 kilometers, liters/meter, miles/gallon (UK) (mpg), and miles/gallon (US) (mpg). Instantly convert one unit to all others.

Fuel is any combustible matter used to maintain fire or gas and create heat or energy. It is a substance that changes form through a process to produce heat, power, and other forms of energy.

There are generally two types of fuel.

**Fossil fuel:**that type of fuel includes coal, oil, and natural gas.**Other fuels:**types of fuel include nuclear fuel (uranium, plutonium, thorium, etc.), hydrogen, and biofuels from biomass (firewood, biodiesel, and ethanol).

Fuel consumption is the amount of fuel consumed per unit of distance.

The formula to measure the fuel consumption in **liters/100 kilometers** is

**(Liters*100)/100 kilometers**

For example, a car uses 100 liters to travel 500km

(100 X 100) ÷ 500 = 20

In the USA, gallons per 100 miles measure fuel consumption. However, in European countries, liters per 100 kilometers are used to measure fuel consumption.

The other measuring units to measure fuel consumption are

- gallons (UK)/100 miles
- kilometer/liter (km/l)
- liters/meter,
- miles/gallon (UK) (mpg)
- miles/gallon (US) (mpg).

The UK gallon is 20% larger than the US gallon, so mpg values are not directly comparable.

Sometimes, people mix these two terms, but they are different from each other.

**Fuel economy** measures the distance a vehicle will travel with a gallon of fuel. It is measured in miles per gallon and is primarily used by the United States, vehicle manufacturers, and regulators to communicate with the public.

**Fuel consumption: **The measure of the fuel consumed per distance unit. It is the inverse of fuel economy. In the USA, gallons per 100 miles are used to measure fuel consumption. However, in European countries, liters per 100 kilometers are used to measure fuel consumption.

The calculation of fuel consumption is helpful because it measures the fuel consumed per 100 miles and can measure volumetric fuel saving. It can also measure the difference in the yearly fuel consumption between two different vehicles if one goes from the vehicle with the provided fuel consumption to the vehicle with less fuel consumption.

After the technological revolution, the most significant change was that the machine replaced the human. We raised the standards in our lives by moving from estimated calculations to proper and accurate calculations.

Even though the machines are built and programmed by humans, they are preferred over humans because they give accurate and correct results within no time.

Moreover, sometimes, you have to convert one fuel consumption measuring unit into another. Our **online** **fuel consumption unit converter **helps you with accurate and precise conversion.

An** online fuel consumption unit converter **makes the conversion process easy. You can easily convert one measuring unit of fuel consumption to another measuring unit within no time.

To do this, follow the steps below.

- Open the
**Online Fuel Consumption Unit Converter Tool**. - Enter the amount
**1**in the first column. - In the second column, "Select from," select gallons (US)/100 miles as a measuring unit you want to convert.
- In the third column, "Select to," select liters/100 kilometers as a measuring unit you want to convert.
- Click on the "convert" button; the result will be 2.3521458333 liters/100 kilometer within no time.

Therefore, 1 gallon (US)/100 miles = 2.3521458333 liters/100 kilometer.

**Note: **You can adopt the same conversion procedure between gallons (UK)/100 miles, gallons (US)/100 miles, kilometers/liter (km/l), liters/100 kilometers, liters/meter, miles/gallons (UK) (mpg), and miles/gallon (US) (mpg).
