What is the equivalent in Watts of 1 BTU per hour?

The correct conversion between BTUs and Watts is based on the definitions of these units of power. Specifically, 1 BTU per hour is equivalent to approximately 0.293 Watts. This is derived from the fact that a BTU (British Thermal Unit) is a unit of energy used to measure heat energy, while a Watt is a unit that measures power (the rate of energy transfer).

To understand this better, it is useful to note that the conversion can be done using the relationship:

1 BTU/hr = 0.29307 Watts.

When you round this value for simplicity, it closely approximates to 0.293 Watts, making it the most accurate answer in this context. This conversion is important in HVAC and refrigeration applications because it allows professionals to translate energy requirements and system capacities between different units, thus enabling better design and analysis of heating and cooling systems.
