Convert Miles per Gallon (UK) to Liters per 100 km instantly with our free online converter. The Miles per Gallon (UK) (mpg (UK)) is miles per gallon (UK/Imperial) — the British fuel economy rating using the larger Imperial gallon (4.546 L), giving higher numbers than US mpg for the same vehicle. The Liters per 100 km (L/100km) is liters per 100 kilometers — the European standard for fuel consumption, measuring how many liters are needed to travel 100 km; lower is more efficient. To convert Miles per Gallon (UK) to Liters per 100 km, divide 282.481 by the mpg (UK) value: L/100km = 282.481 ÷ mpg. For example, 40 mpg UK = 282.481 ÷ 40 = 7.06 L/100km.
Frequently Asked Questions
How do you convert Miles per Gallon (UK) to Liters per 100 km?
To convert Miles per Gallon (UK) to Liters per 100 km, divide 282.481 by the mpg (UK) value: L/100km = 282.481 ÷ mpg. For example, 40 mpg UK = 282.481 ÷ 40 = 7.06 L/100km.
What is a Miles per Gallon (UK) used for?
The Miles per Gallon (UK) (mpg (UK)) is miles per gallon (UK/Imperial) — the British fuel economy rating using the larger Imperial gallon (4.546 L), giving higher numbers than US mpg for the same vehicle.
What is a Liters per 100 km used for?
The Liters per 100 km (L/100km) is liters per 100 kilometers — the European standard for fuel consumption, measuring how many liters are needed to travel 100 km; lower is more efficient.
What is good fuel economy for a car?
A fuel-efficient compact car achieves 5–6 L/100km (40–47 MPG). An average family sedan uses 7–9 L/100km (26–34 MPG). SUVs and larger vehicles typically use 10–14 L/100km (17–24 MPG). Hybrid vehicles achieve 4–5 L/100km (47–59 MPG). Plug-in hybrids and EVs use 15–20 kWh per 100 km.
How far can a car go on a full tank?
With a 55-liter tank and average fuel consumption of 8 L/100km, a car can travel about 687 km (427 miles) on a full tank. A more efficient car at 6 L/100km with the same tank goes about 917 km (570 miles). Most cars have a range of 500–800 km per fill-up under normal driving conditions.
How much does it cost to fill up a car in Europe vs the US?
European petrol prices are typically €1.50–2.00 per liter ($1.60–2.15/L). In the US, gasoline averages $0.95–1.30 per liter ($3.50–5.00 per US gallon). To fill a 55-liter tank: roughly €83–110 in Europe vs. $52–72 in the US. European cars tend to be more fuel-efficient to compensate for higher fuel prices.
What does L/100km mean and how do I read it?
L/100km means how many liters of fuel your car consumes per 100 kilometers traveled. Lower is better — 5 L/100km is more efficient than 10 L/100km. To convert to US MPG, divide 235.215 by the L/100km value: 8 L/100km = 235.215 ÷ 8 = 29.4 MPG.
How fuel-efficient are electric vehicles compared to petrol cars?
Electric vehicles (EVs) use 15–20 kWh per 100 km, which is equivalent to about 1.5–2 L/100km of gasoline in energy terms — roughly 4–5× more efficient than combustion engines. At an electricity price of €0.30/kWh, driving 100 km costs about €4.50–6.00, compared to €12–16 for a petrol car at €1.60/L and 8 L/100km.
