Why convert heat flux from per minute to per hour?

Converting to an hourly basis standardizes heat flux measurements over longer periods, simplifying HVAC design and energy compliance processes.

What is the conversion factor between these units?

1 Btu (th)/minute/square foot equals 60 Btu (th)/hour/square foot because there are 60 minutes in an hour.

Can this conversion be used for fluctuating heat flux values?

The conversion assumes consistent heat flux; rapid changes should be analyzed with more detailed, time-resolved methods.
