FAQ

Why is the km/L to L/100km conversion a division?

km/L measures distance per fuel unit (higher is better), while L/100km measures fuel per distance (lower is better). They are reciprocals scaled by 100: L/100km = 100 ÷ km/L.

How do I quickly estimate L/100km from km/L?

Divide 100 by the km/L value. A car getting 15 km/L uses 100 ÷ 15 = 6.67 L/100km.

Which metric is more common globally?

L/100km is standard in Europe, Australia, and Canada. km/L is common in Japan, India, and parts of South America. Both are metric system units.

Is 20 km/L fuel efficient?

20 km/L equals 5 L/100km, which is very efficient for a gasoline car. This is typical of small hybrids and diesel compacts.

How do you convert kilometers per liter to liters per 100km?

Apply the formula L/100km = 100 ÷ km/L. For example, kilometers per liter of 0 corresponds to Infinity liters per 100km.

How do you convert liters per 100km back to kilometers per liter?

Use the inverse formula: km/L = 100 ÷ L/100km.

Why isn't kilometers per liter-to-liters per 100km a simple multiplication?

Kilometers per Liter and Liters per 100km use different zero points, so the relationship includes both a scale factor and an offset. The scale factor alone gives the rate of change but not the absolute value.
