Frequently Asked Questions
-
Why convert kilojoule/second to Btu (th)/hour?
-
This conversion helps express power ratings in units familiar to HVAC and thermal system design, facilitating specification of heating or cooling loads.
-
Is Btu (th)/hour used worldwide?
-
The Btu (th)/hour unit is primarily used in the United States and may have limited application internationally.
-
Does this conversion work for transient thermal conditions?
-
No, the conversion assumes steady-state power transfer and does not account for temporary or changing thermal conditions.
Key Terminology
-
Kilojoule per second (kJ/s)
-
A unit of power representing energy transfer at 1,000 joules per second, equivalent to one kilowatt.
-
Btu (th)/hour
-
A power unit denoting one thermochemical British thermal unit of heat transferred per hour, used mainly in HVAC and thermal applications.
