Which unit is Watt?
Watts (W) and Kilowatts (kW):
Watts are the SI unit of power. Kilowatts are equivalent to 1,000 Watts and are the most frequently used unit of electrical power. Power in general is defined as energy over time. Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s.
How do I calculate power?
Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W .
