BTU/hr
The British Thermal Unit per hour (BTU/hr) is a unit of power used to describe the rate of heat energy transfer. One BTU is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. When expressed as BTU per hour, it indicates the amount of heat energy transferred per hour. This unit is commonly used in heating, ventilation, and air conditioning (HVAC) systems to specify the cooling or heating capacity of an appliance. It is also used in the context of power generation and thermal energy production.
Milliwatts
A milliwatt (mW) is a unit of power equal to one thousandth of a watt. It is often used in contexts where power levels are low, such as in electronics and communications.
