How to convert megajoules per cubic meter to kilowatt-hours 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 MJ/m³, b for the intermediate value in J/m³, and y for the result in kWh/L.
kWh/L = MJ/m³ × 1000000 ÷ 3600000000
Worked examples
10 MJ/m³ ≈ 0.00277777777778 kWh/L
Step 1: (10 × 1000000) ≈ 10000000 J/m³.
Step 2: 10000000 ÷ 3600000000 ≈ 0.00277777777778 kWh/L.20 MJ/m³ ≈ 0.00555555555556 kWh/L
Step 1: (20 × 1000000) ≈ 20000000 J/m³.
Step 2: 20000000 ÷ 3600000000 ≈ 0.00555555555556 kWh/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 Megajoules per cubic meter
Megajoules per cubic meter (MJ/m³) measures fuel efficiency volume under the conventions above. The base value in J/m³ is (x × 1000000), where x is the numerical value in MJ/m³. Factors shown here are rounded for display; calculations use the stored factor.
