Frequently Asked Questions
-
What does Btu (IT)/pound/°R measure?
-
It measures specific heat capacity in US customary units as the heat required to raise 1 pound of a substance by 1 degree Rankine.
-
Why convert from Btu (IT)/pound/°R to kilocalorie (th)/kilogram/°C?
-
This conversion is useful for integrating legacy US customary heat capacity data with modern metric-based engineering and scientific calculations.
-
Can this tool account for changes in specific heat due to temperature?
-
No, the tool assumes consistent temperature scale equivalencies and does not adjust for variations in specific heat values with temperature or material composition.
