In what situations is Btu (IT)/minute/square foot preferred?

It is preferred when specifying heat loss or gain through building envelopes in HVAC load calculations, and for assessing surface heat transfer or solar heat gain in building and industrial systems.

Are there any precision considerations when using this conversion?

Yes, specifying heat flux density per minute may require more detailed data and could add complexity in analyses that assume steady-state conditions over longer periods.
