-
Results assume International Table unit definitions and steady-state conditions
-
Transient heat transfer or non-uniform areas can affect conversion accuracy
-
Discrepancies may occur if alternative unit definitions are in use
Frequently Asked Questions
-
What does kilocalorie (IT)/hour/square meter measure?
-
It measures the rate of heat transfer per unit area with energy expressed in International Table kilocalories transferred hourly through one square meter.
-
How is Btu (IT)/minute/square foot used in engineering?
-
It quantifies heat flux density as one British thermal unit transferred per minute over one square foot, commonly used in thermal and HVAC calculations.
-
Can this conversion be used for transient heat flow calculations?
-
This conversion assumes steady-state heat transfer and uniform area; it may not be applicable in transient or variable heat transfer conditions.
