What does foot pound/minute/square foot measure?

It measures heat flux density as the amount of energy transferred per unit time and area using imperial units of foot pounds per minute over a square foot.

When should I convert from foot pound/minute/square foot to Btu (th)/second/square foot?

This conversion is helpful when updating legacy imperial heat flux data to standard engineering units for modern thermal calculations and equipment specifications.

Can this conversion be used for SI unit calculations?

No, this conversion specifically relates two imperial heat flux density units and does not directly convert to SI heat flux units without further scaling.
