Joule is a measurement of energy, while Watt is a measurement of Energy over time.
Watt can be written as: J/s
The commercial unit of electricity is typically measured in kilowatt-hours (kWh), while the SI unit of energy is measured in joules (J). One kilowatt-hour is equal to 3.6 million joules.
There are 3.6 million joules in one kilowatt-hour.
1 kilowatt hour means 1000 watts for 3600 seconds, so a kWh equals 3.6 million Joules.
1 kWh = 3.6 x 106 joules. In engineering notation, that's 3.6E6.
One kilowatt-hour, or KWH.Additional AnswerYou don't 'consume power'; you consume energy. Power is a measure of the rate at which you consume energy.
The commercial unit of electricity is typically measured in kilowatt-hours (kWh), while the SI unit of energy is measured in joules (J). One kilowatt-hour is equal to 3.6 million joules.
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
A BTU is about 1055 joules. A kilowatt is 1000 joules/second, so it is 3,600,000 joules/hour. Dividing that by 1055 joules gives you the equivalent of about 3400 BTU/hour.
There are 3.6 million joules in one kilowatt-hour.
The energy 1 kilowatt-hour (kWh) is 3600000 joules.AnswerThere is no such thing as a 'kilowatt per hour'. You probably mean 'kilowatt hour'?
Kilowatt is a measure of the rate of energy use. It is 1,000 Watts or 1,000 Joules per second. A kilowatt hour is 1,000 Joules per second for 3,600 seconds or 3,600,000 Joules. This means a Kilowatt hour not a rate but a measure of total energy used.
There are 3.6 million joules in one kilowatt-hour (kWh).
Joules x 0.000000278 = kW/h
Watt, kilowatt, or megawatt are units of power (energy/time). A watt is 1 joule/second. A kilowatt is a thousand joules per second. A kilowatt is also 1 kWh/hour (kilowatt-hour / hour). Since you would usually pay per kilowatt-hour, you might be more interested in the number of kilowatt-hours. A megawatt is a million joules per second - or a thousand kWh/hour.
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules
It is a unit of energy. If energy is transferred at a rate (power) of one kilowatt, during one hour, then one kilowatt-hour (kilowatt times hour) of energy will be transferred. Since a joule is equal to a watt-second, a kilowatt-hour is the same as 3.6 million joules.
A measure of electrical energy equivalent to one kilowatt hour is a unit of energy equal to 3.6 million joules.
