What is a watt in power measurement?

A watt (W) is the SI derived unit of power equal to one joule of energy transferred per second, indicating the rate of energy usage or production.

Why is Btu (IT)/hour used in HVAC?

Btu (IT)/hour expresses the rate of heat transfer, making it ideal for rating heating and cooling capacity in HVAC equipment.

How do I convert watts to Btu (IT)/hour?

Multiply the power value in watts by 3.4121416331 to obtain the equivalent power in Btu (IT)/hour.
