About Fuel Economy Conversions
Two regions measure fuel economy in opposite directions. The US uses miles per gallon, where higher is better; most of Europe uses liters per 100 kilometers, where lower is better. That inversion is what makes the mental math hard: 30 US MPG works out to about 7.84 L/100km, and 5 L/100km comes to about 47 MPG. The gallon adds a second trap, since a UK gallon is larger than a US one, so the same car rates about 20% higher in UK MPG. All three standards convert on exact factors below.

Frequently Asked Questions
How do I convert Miles per Gallon (UK) to Liters per 100km?
To convert Miles per Gallon (UK) to Liters per 100km, use the conversion where 1 Mile per Gallon (UK) (mpg (UK)) = 282.481 Liters per 100km (L/100km). For example, 1 Mile per Gallon (UK) = 282.481 Liters per 100km.
What are common Mile per Gallon (UK) to Liter per 100 km conversions?
Here are common conversions: 1 Miles per Gallon (UK) = 282.481 Liters per 100km, 5 Miles per Gallon (UK) = 56.4962 Liters per 100km, 10 Miles per Gallon (UK) = 28.2481 Liters per 100km, 25 Miles per Gallon (UK) = 11.2992 Liters per 100km, 50 Miles per Gallon (UK) = 5.64962 Liters per 100km, 100 Miles per Gallon (UK) = 2.82481 Liters per 100km.
When would I need to convert Miles per Gallon (UK) to Liters per 100km?
Fuel economy conversions come up when comparing vehicle efficiency ratings across countries. The US uses miles per gallon (MPG), Europe uses liters per 100 kilometers (L/100km), and the UK uses imperial MPG, which differs from US MPG.
How precise are the conversions?
All conversions use exact factors verified against NIST and ISO standards with up to 10 significant figures of precision. Results are calculated using IEEE 754 double-precision arithmetic, which provides approximately 15-17 significant digits. For temperature and other non-linear conversions, exact formulas are used rather than approximations.
