About the units

Watt (W)

The SI unit of power: one joule per second. An LED bulb draws around 10 W, a microwave about 1,000 W.

Ton of refrigeration (TR)

12,000 BTU/h (about 3.517 kW), historically the cooling from melting one short ton of ice per day. One ton of refrigeration equals 3,516.852842 watts (W).
