About watts
The Watt (W) is the SI unit of power, equivalent to one Joule per second. It is named after James Watt, the inventor of the modern steam engine. It is the standard for measuring electrical power worldwide, from LED bulbs to supercomputers. watts are commonly used in Light bulbs, Electronics, Speakers, and Scientific data, Cycling (power output).
A typical LED bulb uses about 9 Watts.
About BTU per hour
BTU per hour is the standard unit for HVAC (Heating, Ventilation, and Air Conditioning) in the United States. Confusingly, people often drop the 'per hour' and just say 'This AC is 12,000 BTUs', which technically refers to energy, not power. But in the context of appliances, it always means BTU/h. BTU per hour are commonly used in Air conditioners, Gas grills, Space heaters, and Refrigerators, Furnaces.
A small window AC unit is 5,000 BTU/h.
