Liters per 100 km to MPG (US) Converter (L/100 km to mpg)
US mpg = 235.215 ÷ L/100 km. Convert European, Canadian and Australian fuel consumption figures to US miles per gallon, with both charts.
mpg (US) = 100 × 3.785411784 ÷ (1.609344 × L/100 km)
Liter per 100 Kilometers (L/100 km): Liters per 100 kilometers measures fuel used over a distance of 100 km. Lower values mean less fuel for that distance, and 5 L/100 km equals 20 km/L. Reciprocal conversions require finite values greater than zero.
Mile per Gallon (US) (mpg (US)): Miles per gallon (US) is the fuel-economy figure on US window stickers: how many miles a vehicle travels on one US gallon (3.785411784 L). Higher is better; 1 mpg (US) is about 0.4251 km/L.
| Liter per 100 Kilometers (L/100 km) | Mile per Gallon (US) (mpg (US)) |
|---|---|
| 1 | 235.214583333 |
| 5 | 47.0429166667 |
| 10 | 23.5214583333 |
| 25 | 9.40858333333 |
| 50 | 4.70429166667 |
| 100 | 2.35214583333 |
Car makers in Europe, Canada and Australia publish fuel consumption in liters per 100 kilometers, and a US reader comparing a car reviewed abroad with one on a US window sticker needs miles per gallon. Lower is better in L/100 km and higher is better in mpg, so 5 L/100 km describes a thrifty car and 47 mpg is the same thing seen from the other side.
Watch the gallon. Canada's official ratings and UK motoring figures use the imperial gallon when they give mpg, which makes their mpg numbers about 20% higher than US mpg for the same car. This converter gives US mpg; divide the US figure by 0.8327 to get imperial mpg.
How to use this tool
- Type a value in the Liter per 100 Kilometers box to see it in miles per gallon (US), or type in the Mile per Gallon (US) box to convert the other way.
- Press ⇄ to swap the two units, or Load example for a typical value.
- Check the charts below for common values; for other units, open the Fuel Economy converter.
Formula
mpg (US) = 100 × 3.785411784 ÷ (1.609344 × L/100 km)
L/100 km = 100 × 3.785411784 ÷ (1.609344 × mpg (US))
The two units are reciprocals of each other: a value in one times the matching value in the other always gives 235.214583333, so a larger number on one side means a smaller number on the other.
Example
Two conversions worked with the same factors the converter uses:
6.5 L/100 km ≈ 36.1869 mpg (US)
35 mpg (US) ≈ 6.72042 L/100 km

|---|---|---|
| Small hybrid hatchback, a typical rating | 4 | 58.8036 |
| Compact petrol car, a typical rating | 6 | 39.2024 |
| Midsize SUV, a typical rating | 9 | 26.135 |

Quick mental estimate
Divide 235 by the L/100 km figure: 6.5 L/100 km → 235 ÷ 6.5, about 36 US mpg. The exact constant is 235.215, so the shortcut is within 0.1%; rounding to a whole mpg matters more.
Use the converter or the charts when the exact figure matters.
The two units
Liter per 100 Kilometers (L/100 km): Liters per 100 kilometers measures fuel used over a distance of 100 km. Lower values mean less fuel for that distance, and 5 L/100 km equals 20 km/L. Reciprocal conversions require finite values greater than zero.
Mile per Gallon (US) (mpg (US)): Miles per gallon (US) is the fuel-economy figure on US window stickers: how many miles a vehicle travels on one US gallon (3.785411784 L). Higher is better; 1 mpg (US) is about 0.4251 km/L.
Frequently asked questions
What is 6 L/100 km in mpg?
About 39.2 mpg in US gallons, or about 47.1 mpg in UK imperial gallons. That puts a European compact rated at 6 L/100 km roughly level with a 39 mpg rating on a US sticker, before any test-cycle differences.
How do I convert L/100 km to km/L?
Divide 100 by the figure: 8 L/100 km works out to 12.5 km/L. The km/L to mpg converter then takes km/L to US mpg.
Why are European and US figures for the same car hard to compare?
Besides the units, the official tests differ: Europe uses the WLTP procedure, while the US uses EPA tests with their own adjustments. Converting units makes the numbers comparable in form, but not always in the driving they represent.
How precise is the result?
The converter uses the exact definitions above with browser floating-point arithmetic and shows up to 12 significant digits. The charts round to four decimal places for reading.
