# What are watts?

Watt is a derived unit in SI for the power; the symbol is W. The basic units: 1 W = 1 kg.m2/s3. The most used multiples arekilowatt (1000 W) and megawatt (1 million watts).

A watt is the SI unit of power. It's equivalent to one joule per second.

The watt is a unit of power . It is a Newton meter persecond, or can be given as a joule per second. We often encounterit in electrical calculations, and it is the unit of po…wer forapplications there. The formula for power is given here: P = I x E In this expression, the power (P) in watts is equal to the current(I) in amps (or amperes, if you prefer) times the voltage (E) involts. The simplest example of a watt would be the amount of power thatyou would have if you had one volt at one amp of current. Or, toput it another way, 1 volt X 1 Amp=1 Watt. To go further, 12 voltsat 1 amp equals 12 watts. This is for direct current measurement. For AC voltage, it varies in that you would multiply the volts by.707 (AC RMS voltage), then multiply by the amps to get your wattstotal. (MORE)

possibly yes, but he was a instrumental maker trying to or improved steam engine powered stuff.

James Watt was a pioneer in the development of steam technology. Steam engines were used to deliver mechanical power for many applications. Later in the 19th century when in…vestigators began setting up a system to assign definite qualitative and quantitative parameters across science and technological areas, the unit of power was given the name watt to honor James Watt for his work.

Watts is a measure of power, which is the amount of energy in Joules flowing every second.

It's unfortunate that both of these units include the same word "watt". That gives the impression that one can be converted into the other. These two units are used for m…easuring different quantities. They have different physical dimensions, and neither one can be converted to the other. (One hint that this is so is the fact that they have different names.) The "watt" is a unit of power. It measures how fast energy is being transferred. It's equal to one joule of energy per second. The "watt-hour" is a unit of energy. It's equal to the amount of energy transferred in an hour at the rate of one joule per second. So it's equal to 3,600 joules of energy. The rate at which energy is transferred can't be converted into the amount of energy that's transferred, just as the speed of your car can't be converted into the distance you drive. (MORE)

I guess that means 100 watts but hecto- is a prefix that is neverused for electrical quantities. The common ones are milli (.001),kilo (1000) and Mega (1,000,000).
