How to convert kilowatt-hours per liter to megajoules per liter
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 kWh/L, b for the intermediate value in J/m³, and y for the result in MJ/L.
MJ/L = kWh/L × 3600000000 ÷ 1000000000
Worked examples
10 kWh/L ≈ 36 MJ/L
Step 1: (10 × 3600000000) ≈ 36000000000 J/m³.
Step 2: 36000000000 ÷ 1000000000 ≈ 36 MJ/L.20 kWh/L ≈ 72 MJ/L
Step 1: (20 × 3600000000) ≈ 72000000000 J/m³.
Step 2: 72000000000 ÷ 1000000000 ≈ 72 MJ/L.
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 Kilowatt-hours per liter
Kilowatt-hours per liter (kWh/L) measures fuel efficiency volume under the conventions above. The base value in J/m³ is (x × 3600000000), where x is the numerical value in kWh/L. Factors shown here are rounded for display; calculations use the stored factor.
About Megajoules per liter
