Liters per 100 kilometers (L/100km) is the standard fuel efficiency unit in most countries, especially in Europe. It measures how many liters of fuel a car uses to travel 100 kilometers. A typical compact car averages 5–7 L/100km, while SUVs usually range between 8–12 L/100km. This unit is especially useful when comparing electric or hybrid cars. Fuel consumption measured in UK gallons per 100 kilometers. Commonly used in British technical specifications for vehicles in metric markets. Since 1 UK gallon = 4.54609 liters, this unit can be directly converted to L/100km by multiplying by 4.54609. For example, 4 gal/100km (UK) = 4 × 4.54609 ≈ 18.18 L/100km.
To convert between Liters per 100 Kilometers (L/100km) and Gallons per 100 Kilometers (UK) (gal/100km (UK)), use the following formulas:
1 Liters per 100 Kilometers (L/100km) = 0.21996924829908776 Gallons per 100 Kilometers (UK) (gal/100km (UK))
1 Gallons per 100 Kilometers (UK) (gal/100km (UK)) = 4.54609 Liters per 100 Kilometers (L/100km)
5 L/100km = 5 * 0.21996924829908776 gal/100km (UK) = 1.0998462414954389 gal/100km (UK)
6 L/100km = 6 * 0.21996924829908776 gal/100km (UK) = 1.3198154897945265 gal/100km (UK)
7 L/100km = 7 * 0.21996924829908776 gal/100km (UK) = 1.5397847380936143 gal/100km (UK)
10 L/100km = 10 * 0.21996924829908776 gal/100km (UK) = 2.1996924829908777 gal/100km (UK)
15 L/100km = 15 * 0.21996924829908776 gal/100km (UK) = 3.2995387244863164 gal/100km (UK)
