The UK officially uses the Imperial gallon for fuel and most commercial purposes, though the metric system (litres) is the legal standard. Historical UK gallon references typically mean Imperial gallons, which are 4.54609 litres. Most modern UK measurements, especially for fuel at the pump, are displayed in litres.
To convert litres per 100km (L/100km) to miles per gallon (MPG), use the formula: MPG (UK) = 282.48 ÷ L/100km, or MPG (US) = 235.21 ÷ L/100km. For example, 7 L/100km equals about 40.35 MPG (UK) or 33.6 MPG (US).
Common conversions include: 1 litre = 0.264 US gal / 0.220 UK gal, 5 litres = 1.32 US gal / 1.10 UK gal, 10 litres = 2.64 US gal / 2.20 UK gal, 20 litres = 5.28 US gal / 4.40 UK gal, and 50 litres = 13.2 US gal / 11.0 UK gal.
