Global Fuel Calculatorkm/L to MPG Converter
Convert kilometres per litre — the everyday fuel-economy figure across South Asia, Japan and much of the Middle East — into miles per gallon, in both US and imperial terms, or into L/100km. Unlike the MPG/L-100km pair, km/L and MPG move in the same direction: a higher number is better on both scales.
That shared direction makes km/L to MPG an easier conversion to sanity-check than an L/100km one, but the US-versus-imperial gallon split still applies in full, so the same km/L figure produces two different MPG answers depending on which market you are converting for.
km/L to MPG Converter
Common questions
How do I convert from km/l to mpg?
Multiply km/L by about 2.352 for US MPG, or by about 2.825 for imperial MPG. Fifteen km/L converts to roughly 35.3 US MPG or 42.4 imperial MPG.
How much is 40 mpg in km/l?
Divide 40 by 2.352 for the US-gallon basis, giving about 17 km/L, or divide by 2.825 for the imperial basis, giving about 14.2 km/L. Which one applies depends on whether the original 40 MPG was a US or UK figure.
What is 12 litres per 100 km in mpg?
First convert to km/L by dividing 100 by 12 (about 8.33 km/L), then apply the km/L to MPG factors above: roughly 19.6 US MPG or 23.5 imperial MPG.
What is 30 mpg in litres?
Meant as L/100km: divide 235.214 by 30 for a US-gallon basis (about 7.84 L/100km) or 282.481 by 30 for an imperial basis (about 9.42 L/100km). In km/L terms that is roughly 12.8 or 10.6 km/L respectively.
Is 20 km/L a good figure?
Yes, for a car — that is a genuinely efficient result, more typical of a small hybrid or an economical hatchback than an average family car. Motorcycles routinely exceed it by a wide margin.
How do I convert 10 km/L to MPG?
Multiply by 2.352 for about 23.5 US MPG, or by 2.825 for about 28.2 imperial MPG. Enter 10 into the converter above to see both alongside the L/100km equivalent.
