How to convert joules per liter to liters per kilowatt-hour
This is volumetric energy content, not road fuel economy. A heating value needs a defined fuel composition and physical state. Liters per kWh is reciprocal to kWh per liter.
Use x for the value in J/L, b for the intermediate value in J/m³, and y for the result in L/kWh.
b = (x × 1000); y = 3600000000 ÷ b
Worked examples
10 J/L ≈ 360000 L/kWh
Step 1: (10 × 1000) ≈ 10000 J/m³.
Step 2: 3600000000 ÷ 10000 ≈ 360000 L/kWh.20 J/L ≈ 180000 L/kWh
Step 1: (20 × 1000) ≈ 20000 J/m³.
Step 2: 3600000000 ÷ 20000 ≈ 180000 L/kWh.
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 Joules per liter
Joules per liter (J/L) measures fuel efficiency volume under the conventions above. The base value in J/m³ is (x × 1000), where x is the numerical value in J/L. Factors shown here are rounded for display; calculations use the stored factor.
About Liters per kilowatt-hour
Liters per kilowatt-hour relates inversely to Joules per cubic meter. The base value is 3600000000 ÷ x, where x is the numerical value in L/kWh. A zero or negative reciprocal input is outside this calculator’s physical domain.
