Frequently Asked Questions
-
What does joule per kilogram measure?
-
Joule per kilogram (J/kg) measures the specific energy or enthalpy per unit mass, indicating how much energy is contained or released per kilogram.
-
Why convert from J/kg to pound per Btu (IT)?
-
Converting to pound per Btu (IT) is useful for fuel consumption analysis, boiler sizing, and relating fuel mass to heat energy in combustion contexts.
-
Is the conversion affected by fuel types?
-
This conversion uses standard unit definitions and does not account for variations in fuel composition or efficiency.
