What does CHU/hour/square foot measure?

CHU/hour/square foot measures heat flux density as the rate of thermal energy transfer per hour across one square foot of area.

When should I convert heat flux density from CHU/hour/square foot to Btu (th)/second/square inch?

Convert between these units when needing precise imperial unit measurements for small-area, second-based heat flux, especially in engineering tests and fire-protection work.

Why is handling small numerical values important in this conversion?

Because the conversion factor is very small, careful handling prevents rounding errors that could compromise the accuracy needed in engineering calculations.
