What Is This Tool?
This converter helps transform values expressed in liter per joule (L/J), a volume per unit energy metric, into kilojoule per cubic meter (kJ/m^3), a volumetric energy density unit. It enables easy switching between volume-based fuel requirements and energy content per volume for practical applications in fuel and energy fields.
How to Use This Tool?
-
Enter the value in liter per joule (L/J) you want to convert
-
Select the source unit as liter/joule and the target unit as kilojoule/cubic meter
-
Click convert to see the equivalent energy density in kJ/m^3
Key Features

-
Fuel composition differences affect energy content and may impact conversion accuracy
Frequently Asked Questions
-
What does liter per joule measure?
-
Liter per joule (L/J) indicates the volume of fuel in liters needed to supply one joule of energy.
-
Why convert liter/joule to kilojoule/cubic meter?
-
Converting between these units helps relate fuel volume requirements to energy content per volume, facilitating engineering and energy management analyses.
-
Are the conversion values always equal?
-
Yes, the conversion rate is 1 L/J equals 1 kJ/m^3 under consistent conditions.
Key Terminology
-
Liter per joule (L/J)
-
A measure of the volume of fuel in liters needed to produce one joule of energy; inverse of volumetric energy density.
-
Kilojoule per cubic meter (kJ/m^3)
-
A unit quantifying the energy contained, in kilojoules, within one cubic meter of fuel or gas.
