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

SI to Imperial Conversion

You are converting from a si unit to a imperial unit. This conversion is commonly needed when:
