What does CHU/hour/square foot measure?

It measures heat flux density as the amount of CHUs of thermal energy transferred per hour across one square foot of surface area.

Why convert CHU/hour/square foot to watt/square inch?

Converting to watt/square inch allows precise thermal analysis and management of small-area components, such as electronic devices or focused heat sources.

Can this conversion be used for general power measurements?

No, this tool is specific to heat flux density units and should not be used for unrelated power or energy unit conversions.
