Tons of refrigeration: A ton of refrigeration (RT) is a unit of power used to describe the heat-extraction capacity of air conditioning and refrigeration equipment. One ton of refrigeration is equal to the rate of heat transfer needed to freeze 1 ton (2000 pounds) of water at 0°C in 24 hours, equivalent to 12,000 BTU per hour or approximately 3.517 kilowatts.
Gigawatt: The gigawatt (GW) is a unit of power equal to one billion watts. Gigawatts are used to measure the capacity of very large power plants and the total power consumption of entire countries. For example, the total electrical generating capacity of a large nuclear power plant can be around 1 gigawatt.
