What does CHU/hour/square foot measure?

It measures heat flux density as the rate of thermal energy transferred per hour across one square foot.

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

Because it expresses thermal power per unit area per second, useful for high intensity and rapid heat flux analysis.

Is the conversion affected by measurement conditions?

No, the conversion assumes standard conditions and does not consider variations in environment or measurement setup.
