To convert liters per 100 km to miles per gallon (US), use mpg = 235.2146 ÷ L/100 km. Fuel consumption (L/100 km) is the inverse of fuel economy, so you divide rather than multiply. For example, 5 L/100 km = 47.0429 mpg.
What does this tool do?
This l/100km to mpg converter converts fuel economy units such as km/l, mpg and litres per 100 km the moment you type — no buttons to press, no page reloads. The converted value appears with the formula used, so you can see exactly how the answer was produced and reuse it in homework, bills or documents. A swap button (⇄) reverses the direction instantly, and the From and To dropdowns give you every fuel economy unit the converter knows, not just this pair. A “Copy result” button puts the answer on your clipboard for pasting into WhatsApp, Excel or a quotation.
The L/100km to MPG Converter is free of the usual catches: no watermark on results, no “three free uses” counter, no app install nagging. It does the job and gets out of the way, which is all a utility should do.

L/100km to MPG formula
mpg = 235.2146 ÷ L/100 km
Fuel consumption (L/100 km) is the inverse of fuel economy, so you divide rather than multiply.
Example: 5 L/100 km = 47.0429 mpg.
Reverse: 1 mpg = 235.21458 L/100 km (see MPG to L/100km).

What are these units?
Liters per 100 km (L/100 km): Fuel used per 100 km; lower is better. Used in Europe and Australia.
Miles per gallon (US) (mpg): Miles per US gallon.
Use cases in Pakistan
Fuel economy is watched closely with petrol prices in Pakistan. Car owners compare mileage in km per litre, while imported car reviews and brochures quote miles per gallon or litres per 100 km; converting lets you judge whether a hybrid’s claimed average beats your Suzuki or Corolla. Fleet owners and Careem/InDrive drivers track fuel cost per kilometre, which starts from an accurate economy figure in familiar units.
These are the tools people recommend to each other on WhatsApp — simple, free, no install — because they solve the small problems everyone hits: timing something, picking fairly, testing a device. Bookmark the ones you use; they age well.
Limitations
Economy figures are exact conversions of the stated figure, but real mileage depends on driving style, traffic, AC use and fuel quality — treat brochure figures as optimistic. Note that “litres per 100 km” runs inverse to the others: a smaller number means better economy.
Convenience tools are not certified instruments: fine for everyday purposes, but do not stake safety, money or legal outcomes on a browser utility. Know which category your use falls into.
Frequently asked questions
How many miles per gallon (US) are in a liters per 100 km?

What is the formula to convert liters per 100 km to miles per gallon (US)?
Litres per 100 km runs inverse to the other fuel-economy units: a smaller number means better economy. The converter applies the exact inverse relationship to your value and shows the result with up to 10 significant figures.
How do I convert miles per gallon (US) back to liters per 100 km?

Can I convert between other fuel economy units?
Yes. The From and To dropdowns list all 4 fuel economy units this converter knows — pick any pair, for example Liters per 100 km to kilometers per liter or miles per gallon (uk) to miles per gallon (us).
How accurate is the result?
It uses the exact defined values of both units and displays up to 10 significant figures — far more precision than any ruler, scale or bill needs. The conversion itself introduces no error; only the displayed decimals are rounded.
