A megawatt is 1000 kilowatts (also equal to 1341 horse power) or 1*10^6 watts, a gigawatt is 1000 megawatts. A watt is equal to one joule per second and a joule is defined as the amount of work done when 1 ampre of electrical current is passed through 1 ohm of resistance. Ohm is defined as the amount of electrical resistance of a conductor in which 1 ampre of current is produced by a potential of 1 volt across its terminals.

The watt is the SI unit for power, which is defined as 'the rate of doing work'. Since work is measured in joules, the watt is equivalent to a joule per second.

A megawatt (MW) is one-million watts, and a gigawatt (GW) is a thousand-million watts.

How many watts in a gigawatts?

1000. A megawatt-hour is the energy you'd get with a megawatt of power for 1 hour. Energy = power * time. It's important to note that it's 'megawatt hour' and not megawatt/hour (ie. it's not megawatt per hour).A gigawatt has 1000 times the power of a megawatt. Thus, since the time is the same (both 1 hour), a gigawatt-hour = 1000 megawatt hours.


Can you subtract a megawatt from a gigawatt?

It's a question of scale. A gigaWatt is 1000 megaWatts, so if you subtract one, you are left with 999 megaWatts.

Calculate what a megawatt hour is?

Mega means million and a watt is a unit of power. A megawatt hour is the amount of power used if 1,000,000 watts are used for 1 hour, or 1 watt is used for 1,000,000 hours. If 100 light bulbs each using 1,000 watts of power are turned on for 10 hours, they will use 100 x 1,000 x 10 watt hours = 1,000,000 watt hours = 1 megawatt hour. Most electric companies charge for the number of kilowatt hours used. A megawatt hour is 1,000 kilowatt hours.
