What does watt per square inch (W/in²) measure?

It measures heat flux density as the rate of power (watts) transferred, emitted, or incident over one square inch of area.

Why convert from W/in² to calorie (th)/hour/cm²?

This conversion enables comparison and application of heat flux data between imperial units and thermochemical calorie-based units used in thermal testing and historical data.

Is calorie (th)/hour/cm² commonly used in modern measurements?

It is less common in current SI-based systems and is mostly found in historical literature and certain specialized engineering contexts.
