To convert kilometers per liter to liters per 100 km, use L/100 km = 100 ÷ km/l. Fuel consumption (L/100 km) is the inverse of fuel economy, so you divide rather than multiply. For example, 5 km/l = 20 L/100 km.
What does this tool do?
This km/l to l/100km 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 KM/L to L/100km 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.
How do I use this tool?
The tool is ready the moment the page opens — no setup, no account. The steps below cover everything it does.
- Type the value into the “Kilometers per liter” field.
- Read the converted value in liters per 100 km — the formula used is shown underneath.
- Tap “Copy result” to copy the answer to your clipboard.

KM/L to L/100km formula
L/100 km = 100 ÷ km/l
Fuel consumption (L/100 km) is the inverse of fuel economy, so you divide rather than multiply.
Example: 5 km/l = 20 L/100 km.
Reverse: 1 L/100 km = 100 km/l.

What are these units?
Kilometers per liter (km/l): Used for car fuel average in Pakistan, India and Japan.
Liters per 100 km (L/100 km): Fuel used per 100 km; lower is better. Used in Europe and Australia.
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 liters per 100 km are in a kilometers per liter?
There are 100 liters per 100 km in one kilometers per liter.
How do I convert kilometers per liter to liters per 100 km?
L/100 km = 100 ÷ km/l. Fuel consumption (L/100 km) is the inverse of fuel economy, so you divide rather than multiply. Example: 5 km/l = 20 L/100 km.
What is the formula to convert kilometers per liter to liters per 100 km?
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 liters per 100 km back to kilometers per liter?
Tap the swap button (⇄) above the result — the From and To units exchange places and the value converts back using the exact inverse factor.
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 Kilometers per liter to kilometers per liter or miles per gallon (uk) to liters per 100 km.
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.
