Convert MPG to L/100km

In order to convert MPG to L/100km first we will convert miles to kilometers and gallon to liters.

Convert miles to kilometers

1 mile = 1.609344 kilometers
1 mi = 1.609344 km

Convert US Gallons to liter

1 US gallon = 3.78541178 litres
1 gal = 3.78541178 l

Fuel efficiency is measured as ratio of miles and gallons. We will substitute 1 mile with 1.609 Km & 1 gallon with 3.785 L in this ratio.

Write fuel efficiency in MPG

MPG = miles / Gallon

Substitute Mile & Gallon with Km & L

MPG = 1.609 km / 3.785 L

To convert from fuel efficiency to fuel consumption, we invert the MPG ratio. Then multiply it with constant 100 because its standard in metric system to express fuel consumption per 100 kilometers

Invert MPG to get L/Km units

1 / (Mi/G) = 1 / (km/L) = L/Km
= 3.785 L / 1.609 Km = 2.352 L / Km

Multiply & Divide with 100

2.352 L x 100 / Km x 100
1/MPG= 235.2 L / 100 Km

For converting fuel efficiency in MPG to fuel consumption in L/100Km we need to divide 235.2 by MPG value

Convert MPG to L/100Km using formula

L/100km = 235.214 / MPG

Check MPG for US or Imperial Gallon

To avoid errors in conversion, just confirm whether the «Gallon» value in your Miles per gallon(MPG) is US Gallon or an Imperial UK Gallon.

For Miles per US Gallon to Liter per 100 KM
Divide 235 by your MPG to get liters per 100km. If fuel consumption value is in L/100km, divide it by 235 to get MPG.
For Miles per Imperial Gallon to Liter per 100 KM
Divide 282 by your MPG to get liters per 100km. If fuel consumption value is in L/100km, divide it by 282 to get MPG.
