What does Btu (IT)/second measure?

It measures power as the rate of heat transfer or energy conversion, defined by the International Table British thermal unit per second.

Why convert Btu (IT)/second to millijoule/second?

Converting to millijoule/second allows expressing large heat transfer rates in smaller units suited for low-power or microscopic analyses.

Can this conversion be used for HVAC system design?

Yes, it is commonly used for specifying and comparing thermal power in HVAC components alongside metric units like kilowatts.
