About the units
Watt (W)
The watt is the SI unit of power: one joule per second. A typical LED bulb uses 5 to 10 watts and a kettle around 2,000 watts.
BTU per hour (BTU/h)
BTU per hour is the rate at which heat is moved. Air conditioners and furnaces are rated in it; 12,000 BTU/h is called one ton of cooling and is about 3.52 kilowatts.
