What does watt per square centimeter measure?

It measures the rate of energy transfer in watts through or onto each square centimeter of surface, expressing localized power per unit area.

When should I use calorie (IT) per hour per square centimeter instead of watts?

Use calorie (IT)/hour/cm² when working with older literature, legacy equipment calibration, or protocols that specify heat flux in calorie-based units.

Is the conversion from watt/cm² to calorie (IT)/hour/cm² exact?

The conversion uses a specific factor, but precision may be affected by rounding in the constants, especially for high-accuracy needs.
