Understanding Watt and BTU per Hour
Watt (W)
The watt is a unit of power in the SI system, used for base measurements.
• SI base unit of power, named after James Watt
• Defined as 1 joule per second (1 W = 1 J/s)
• Used for light bulbs, small appliances, electronics
• Standard unit for electrical power worldwide
BTU per Hour (BTU/h)
The btu per hour is a unit of power in the Imperial system, used for thermal measurements.
• Standard for window air conditioners
• Used for space heaters and furnaces
• Common in energy efficiency ratings (SEER)
• Used for fireplace and stove specifications
