Limitations
-
Conversion relies on consistent measurement definitions and does not account for fuel composition variability.
-
Results may vary when fuel physical states or combustion efficiencies differ significantly.
-
Pound per Btu (th) is an inverse of specific energy and should be interpreted with care.
-
This tool does not adjust for temperature, pressure, or other operational conditions impacting thermal properties.
