What does joule/second/square meter measure?

It measures the rate of heat energy flow per unit area, expressed as watts per square meter.

Why convert to Btu (IT)/minute/square foot?

Because this unit is commonly used in thermal and HVAC engineering in regions using imperial measurements, facilitating compatibility with local standards.

Can this converter be used for heat transfer over time?

No, these units represent instantaneous heat flux density and do not capture time-dependent thermal changes.
