Frequently Asked Questions
-
What does joule per kilogram per kelvin represent?
-
It is the SI unit of specific heat capacity, indicating the energy needed to raise the temperature of one kilogram of a substance by one kelvin.
-
Why convert specific heat capacity to pound-force foot per pound per degree Rankine?
-
This allows thermal calculations in Imperial or US customary units especially in power plants, HVAC, and combustion system modeling using Rankine/Fahrenheit units.
-
Are there any differences between Kelvin and Rankine scales in this conversion?
-
While temperature scales differ, the increments are analogous for specific heat, but users must ensure consistent mass and temperature units to avoid errors.
