Frequently Asked Questions

Why are watt/square meter/°C and joule/second/square meter/K equivalent?
Because a temperature difference of one degree Celsius equals one kelvin difference, these units quantify heat transfer per unit temperature difference equivalently.

Can I use this conversion for absolute temperature measurements?
No, this conversion applies only to temperature differences, not absolute temperatures.

What are typical applications of this heat transfer coefficient conversion?
It is used for building energy performance evaluations, HVAC design, heat exchanger sizing, and aerospace thermal management.
