Practical Tips

MPG and L/100km are inversely related — higher MPG means lower L/100km
The formula is: L/100km = 235.215 / MPG (US)

What are common Mile per Gallon (US) to Liter per 100 km conversions?

Here are common conversions: 1 Miles per Gallon (US) = 235.214 Liters per 100km, 5 Miles per Gallon (US) = 47.0429 Liters per 100km, 10 Miles per Gallon (US) = 23.5214 Liters per 100km, 25 Miles per Gallon (US) = 9.40858 Liters per 100km, 50 Miles per Gallon (US) = 4.70429 Liters per 100km, 100 Miles per Gallon (US) = 2.35214 Liters per 100km.

When would I need to convert Miles per Gallon (US) to Liters per 100km?

Fuel economy conversions are needed 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.
