The dimension of power is energy divided by time. The SI unit of power is the watt (W), which is equal to one joule per second. Other units of power include horsepower (hp). One horsepower is equivalent to about 746 watts. Power, as a function of time, is the rate at which work is done. The watt (symbol: W) is a unit of power. In the International System of Units (SI) it is defined as a derived unit of 1 joule per second, and is used to quantify the rate of energy transfer. The watt is named after the Scottish inventor James Watt.
Here are multiples of the watt:
1 Picowatt = 1000 Femtowatts
1 Nanowatt = 1000 Picowatts
1 Microwatt = 1000 Nanowatts
1 Milliwatt = 1000 Microwatts
1 Watt = 1000 Milliwatts
1 Kilowatt = 1000 Watts
1 Megawatt = 1000 Kilowatts
1 Gigawatt = 1000 Megawatts
1 Terawatt = 1000 Gigawatts |
