How to Convert Liters per 100 Kilometers to MPG?
To convert liters per 100 kilometers (L/100 km) into US miles per gallon (mpg), you need to divide a fixed number, which is 235.21, by the fuel consumption value in L/100 km. This number, 235.21, comes from the difference between kilometers and miles as well as liters and gallons. In simple words, the formula is US mpg = 235.21 ÷ (L/100 km). This means you do not multiply, you only divide, and the smaller your L/100 km number is, the higher your mpg result will be.
For example, if a car uses 8 liters of fuel to travel 100 kilometers, you can find out how many miles per gallon it equals in the US system. You take 235.21 and divide it by 8, which gives 29.4 mpg. This shows that a car with a fuel use of 8 L/100 km is about the same as a car that runs 29.4 miles per gallon in the US.
To convert liters per 100 kilometers (L/100 km) into UK miles per gallon (mpg), you also need to divide by a fixed number, but this time the number is 282.48. This value comes from the difference between kilometers and miles as well as liters and the larger UK gallon. In simple words, the formula is UK mpg = 282.48 ÷ (L/100 km). Just like with the US version, you do not multiply, you only divide, and the smaller the L/100 km value is, the higher the mpg result will be in the UK system.
For example, if a car uses 8 liters of fuel to travel 100 kilometers, you can find out how many miles per gallon it equals in the UK system. You take 282.48 and divide it by 8, which gives 35.3 mpg. This shows that a car with a fuel use of 8 L/100 km is about the same as a car that runs 35.3 miles per gallon in the UK.
What is Liters per 100 Kilometers?
Liters per 100 kilometers (L/100 km) is a metric unit used to measure fuel consumption. It tells you how many liters of fuel a vehicle uses to travel 100 kilometers. Unlike miles per gallon (mpg), which measures how far a car can go with one gallon, L/100 km measures how much fuel is needed for a fixed distance. This unit is commonly used in Europe, Canada, and other countries that follow the metric system.
What is MPG?
Miles per gallon, often written as mpg, is a fuel efficiency unit used mainly in the United States and the United Kingdom. It measures how many miles a vehicle can travel on one gallon of fuel. The higher the mpg, the more fuel-efficient the car is. The unit is not a length unit but a measure that combines distance (miles) and volume (gallons) to show how far a car goes with a set amount of fuel. In simple terms, mpg tells drivers how economical their car is.
The history of mpg goes back to the early 20th century when cars became popular, and people needed a way to measure fuel use. Over time, mpg became the standard in English-speaking countries, though the size of a gallon differs between the US and the UK, leading to two versions of mpg. In comparison, most of the world uses liters per 100 kilometers (L/100 km), which shows how much fuel a car uses over a set distance rather than how far it can go. While mpg tells you the distance per gallon, L/100 km tells you the fuel used per distance, but both serve the same purpose—helping drivers understand fuel economy.
