How does the fuel consumption converter work?

It converts between miles per gallon (mpg), liters per 100 km, and kilometers per liter using their standard definitions. Lower l/100km means better efficiency, while higher mpg means better efficiency.

How do I convert mpg to liters per 100 km?

Divide 235.215 by the mpg value. For example, 40 mpg is about 5.88 L/100 km. The converter handles this and the reverse conversion instantly.

What is the difference between US and UK mpg?

A US gallon is 3.785 liters while a UK (imperial) gallon is 4.546 liters, so the same car shows a higher mpg figure in the UK. This converter offers both variants.

What is a good fuel efficiency figure?

A modern efficient car might achieve 40-60 mpg (about 4-6 L/100 km) on the highway, while SUVs and trucks are often 20-30 mpg. The lower the liters-per-100-km, the better.

Which units are used in my country?

Most of the world uses liters per 100 km, the US and UK use mpg, and some countries quote km per liter. This converter supports all three so you can compare vehicles across standards.
