About this tool
Convert kilometers per liter to liters per 100 km instantly. Free, bidirectional, and fully in-browser.
Convert kilometer per liter to liters per 100 km using L/100km = 100 ÷ km/L — type any figure to convert it instantly. This Kilometer per liter to Liter per 100 km converter is a client-side tool: it applies the exact fuel economy formula (L/100km = 100 ÷ km/L) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert liters per 100 km back to kilometers per liter. A reference table lists common kilometer per liter values already converted, and nothing you enter is sent to a server.
Open Kilometer per liter to Liter per 100 km Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Kilometer per liter field.
Read the equivalent in liters per 100 km in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert liters per 100 km to kilometers per liter.
The result updates as you type, and the swap button flips the conversion to liter per 100 km → kilometer per liter without reloading.
The conversion uses the exact formula L/100km = 100 ÷ km/L, so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
Use the formula L/100km = 100 ÷ km/L. For example, 40 km/L = 2.5 L/100km.
