What Is This Tool?
This tool converts specific heat capacity units from Btu (th)/pound/°R, a thermal British unit per pound per degree Rankine, to CHU per pound per degree Celsius. It helps reconcile thermal data expressed using the Rankine scale with Celsius temperature changes while maintaining pounds as the unit of mass.

-
Assumes precise relation between Rankine and Celsius temperature scales
-
Users must maintain consistent mass units and handle temperature interpretations carefully
Frequently Asked Questions
-
Why convert from Btu (th)/pound/°R to CHU/pound/°C?
-
This conversion allows adapting specific heat capacity values from the Rankine temperature scale to Celsius temperature increments while keeping mass units in pounds, facilitating consistent thermal calculations across unit systems.
-
What industries commonly need this unit conversion?
-
Industries such as HVAC design, boiler and heat exchanger engineering, refrigeration, combustion, and industrial food processing often require converting between these units to maintain uniform data integration.
-
Does this tool account for changes in material properties with temperature?
-
No, the tool converts units assuming constant properties and precise temperature scale relations but does not adjust for temperature-dependent variations in substance properties.
Key Terminology
-
Btu (th)/pound/°R
-
Specific heat capacity unit quantifying heat energy in thermal British thermal units needed to raise one pound of substance by one degree Rankine.
-
CHU/pound/°C [CHU/(lb*°C)]
-
Specific heat capacity unit expressing heat energy in CHU required to raise a pound of material by one degree Celsius.
-
Specific Heat Capacity
-
A measure of the amount of heat energy needed to increase the temperature of a unit mass of a substance by one unit change in temperature.
