How to convert liters per kilometer to liters per 100 kilometers

Consumption measures fuel per distance; economy measures distance per fuel. Their relationship is reciprocal. US and imperial mpg use different gallons. Inputs must be positive; zero fuel use would imply infinite economy.

Use x for the value in L/km, b for the intermediate value in L/100 km, and y for the result in L/100 km.

L/100 km = L/km × 100

Worked examples

  • 10 L/km ≈ 1000 L/100 km

    Step 1: (10 × 100) ≈ 1000 L/100 km.
    Step 2: 1000 ÷ 1 ≈ 1000 L/100 km.

  • 20 L/km ≈ 2000 L/100 km

    Step 1: (20 × 100) ≈ 2000 L/100 km.
    Step 2: 2000 ÷ 1 ≈ 2000 L/100 km.

Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.

About Liters per kilometer

Liters per kilometer (L/km) measures fuel consumption under the conventions above. The base value in L/100 km is (x × 100), where x is the numerical value in L/km. Factors shown here are rounded for display; calculations use the stored factor.

About Liters per 100 kilometers
