Frequently Asked Questions
-
What does watt per square centimeter measure?
-
It measures the rate of energy transfer in watts through each square centimeter of surface, representing localized heat flux density or irradiance.
-
How is a joule per second per square meter related to watts per square meter?
-
One joule per second per square meter is equivalent to one watt per square meter, both representing heat energy flow rate per unit area.
-
Why convert from watt/square centimeter to joule/second/square meter?
-
Converting to joule/second/square meter allows users to express localized high-intensity heat flux values in a standard SI unit, aiding comparison and integration across applications.
