Assuming you got that number off an electric kettle it is because that is how much power is needed to heat the water. The number of watts actually measure how much energy the kettle is designed to use. Water is very hard to heat compared to other liquids(or to cool). So it takes a lot of watts to get the kettle to heat the water.

A typical microwave is 750-800 watts. There are lower (and higher) power machines, but the 'normal' for general use is 750-800 watts.

800
Depends upon the voltage. At 110 volts, 800 watts = 7.27 amps. At 115 volts, 800 watts = 6.96 amps. At 120 volts, 800 watts = 6.67 amps. At 220 volts, 800 watts = 3.64 amps. Just divide the wattage by the voltage to determine the amperage. (You can also divide the wattage by the amperage to determine the voltage!)
8,000 watts = 8 kVA / (the power factor) If the power factor is 1, then 8 kVa = 8,000 watts.
a long-distance 800 number.
In the YUK an electric kettle has a 13 amp fuse., together with a 250 voltage. However, in the USA the voltage is lower and so ther fuse amperage may be different.
You can power any amount of devices that total to a sum of 800 watts. If you can not find the wattage on the devices nameplates then use the amperage of the devices. I = W/E, Amps = Watts/Volts. 800/120 = 6.6 amps. A total of 6.6 amps can be used from a 800 watt generator.

Increase in the object's potential energy = (force) x (distance) = (200) x (4) = 800 newton-meters = 800 joulesPower = (800 joules) / (4 seconds) = 200 joules per second = 200 watts
