What does calorie (th)/hour/square centimeter measure?

It measures the rate of heat flow per unit area as one thermochemical calorie transferred per hour across one square centimeter.

When should I use Btu (th)/second/square foot?

It is commonly used in engineering and building science to specify heat transfer rates per unit area in Imperial units.

Why is this conversion important?

It helps translate heat flux density data between older metric measurements and modern Imperial unit applications in HVAC and fire-testing.
