What is a Fuel Consumption Converter?
A fuel consumption converter is a tool that converts between units of fuel economy such as miles per gallon (MPG), liters per 100 kilometers, and kilometers per liter. It is essential for comparing vehicle efficiency across countries that use different measurement standards.
How to Convert Fuel Consumption Units
Select the fuel economy unit you want to convert from and the target unit using the dropdown menus. Enter your value in the input field and the converter instantly calculates the equivalent fuel consumption. Note that MPG and L/100km have an inverse relationship.
Fuel Consumption Conversion Formulas
History of Fuel Consumption Measurement
Fuel economy measurement became important with the rise of automobiles in the early 20th century. The US adopted miles per gallon (MPG), Europe uses liters per 100 km, and Japan uses km/L. The 1970s oil crisis heightened global awareness of fuel efficiency, leading to government-mandated standards.
About This Fuel Consumption Converter
This fuel consumption converter supports 27 units including mile/gallon (US and UK), liter/100 km, kilometer/liter, gallon/mile, gallon/100 miles, and various metric distance-per-volume combinations. It handles both US and UK gallon measurements.
Frequently Asked Questions
How do I convert MPG to L/100km?
Divide 235.215 by the MPG (US) value. For example, 30 MPG = 235.215 ÷ 30 = 7.84 L/100km. For UK MPG, divide 282.481 by the value instead.
What is the difference between US and UK MPG?
UK gallons are larger than US gallons (1 UK gallon = 1.201 US gallons). So the same car gets a higher MPG number in the UK. Multiply US MPG by 1.201 to get UK MPG.
How do I convert km/L to L/100km?
Divide 100 by the km/L value. For example, 15 km/L = 100 ÷ 15 = 6.67 L/100km. These units have an inverse relationship.
Is higher or lower L/100km better?
Lower L/100km is better because it means the vehicle uses less fuel per 100 kilometers. This is opposite to MPG, where higher is better.
How do I convert MPG to km/L?
Multiply the US MPG value by 0.4251 to get km/L. For example, 25 MPG × 0.4251 = 10.63 km/L.
