How many BTUs are equivalent to one watt?

One watt is equivalent to approximately 3.413 BTUs (British Thermal Units) per hour. This conversion is based on the fact that a watt is a unit of power in the International System of Units (SI), which measures the rate of energy transfer.

In HVAC applications, understanding this relationship is essential, as it allows technicians to convert electrical energy usage into heating or cooling capacity. For instance, in cooling systems, most equipment ratings are expressed in BTUs, while electrical consumption is expressed in watts. Thus, knowing how many BTUs are produced per watt helps in evaluating system efficiency and making proper calculations for energy costs and system sizing.

The other options do not correctly reflect the conversion rate between watts and BTUs, making them less relevant in practical applications concerning HVAC efficiency computations.
