Kilowatts and Calculations: What You Need To Know? - Just Energy

WitrynaIn the U.S., electrical energy is usually measured in terms of kilowatt-hours (kWh), because this is a practical unit for the utility company as well as the customer. The relation between kilowatt-hours and joules is easy to determine: 1 kWh = 1,000 J/s x 3,600 s = 3.6 x 10 6 J. WitrynaAs a joule on its own is a small quantity, the kilojoule (kJ), thousands of joules, the megajoule (MJ), millions of joules, and even the gigajoule (GJ), thousands of millions of joules, are all practical units of electrical energy. Thus one unit of electricity which is equivalent to one kilowatt-hour (kWh) can be defined as 3.6 megajoules (MJ).

Did you know?

WitrynaAnswer (1 of 6): 3.6 MJ (mega joules) 1 kWH x 1000 W/kW x 3600 s/h = 3.6 x 10^6 Ws A joule is a watt second. WitrynaTo do this, we simply multiply both sides of the equation by 7.8, which on the left-hand side gives us 7.8 times one kilowatt-hours, so that’s 7.8 kilowatt hours. And on the right-hand side, we’ve got 3600000 multiplied by 7.8 joules. When we evaluate the right- hand side, we find that 7.8 kilowatt-hours ends up being 28080000 joules.
