The rate at which electrical energy is used may be measured in what?
The rate of electrical energy is called Power. The SI unit of Power is the watt (W), which is equal to one joule per second. Other units of power include ergs per second (erg/s), horsepower (hp), metric horsepower (Pferdestärke (PS) or cheval vapeur (CV) and foot-pounds per minute.
1 Watt = 1 Joule/sec
1 KW = 1000 Watts
10,000,000.00 erg/s = 1 Watts
1 horsepower = 745.699872 Watts
1 Metric horsepower = 735.49875 Watts
1 foot-pounds per minute = 0.0225969658 watts
