The joule is the SI unit of measurement for energyor work, whereas the watt is the SI unit of measurement for power.
Work is defined as the process of converting one form of energy into another, e.g. work is done when an electric motor converts electrical energy into kinetic energy.
Power is defined as the rate of doing work, so a watt is equivalent to a joule per second.

Write a relation between commercial unit of electricity and the SI unit of energy?
1 kWh = 3,600,000 joules (or watt-seconds).
How many joules are there in a kilowatt-hour?
These do not have the same units. 1 kilowatt hour per meter cubed is in kg m-1 s-2 1 kilojoule per kg is in m2 s-2
What does liters per kilowatt hour mean?
That means kilowatt times hour - a power of 1 kilowatt, over a time of 1 hour, would give one kilowatt-hour. It is, therefore, a unit of energy (equal to 3,600,000 joules, since a joule is a watt-second).
How many kw in a kj?
1 kWh is a kilowatt-hour, in other words 1000 watts for one hour. That is 1000 Joules per second, for 3600 seconds. So 1 kWh is 3,600,000 Joules, or 3600 kJ.
1kilo watt hour is equal to in jull?
1 kilowatt hour means 1000 watts for 3600 seconds, so a kWh equals 3.6 million Joules.
Write a relation between commercial unit of electricity and the SI unit of energy?
1 kWh = 3,600,000 joules (or watt-seconds).
What is difference between Kilowatt power vs 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.
How many kilowatt hours in one tetra joule?
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
One kilowatt equals how many btu per hour?
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.
How many joules are equivalent to one kilowatt per 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'?
How many joules are there in a kilowatt-hour?
These do not have the same units. 1 kilowatt hour per meter cubed is in kg m-1 s-2 1 kilojoule per kg is in m2 s-2
How do you convert joule to kilowatt-hour?
Joules x 0.000000278 = kW/h
How many units consumed per 24 hours of megawatt mot er?
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.
What does a kilowatt-hour measure?
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.
What is cost of btu?
This depends on the cost per kilowatt hour in your area.
How do you convert 1500 killiwat hours to joule?
1 kilowatt = 1,000 watts1 watt = 1 joule per second1 hour = 3,600 seconds(1,500 kilowatt-hour) x (1,000 watt / kilowatt) x (1 joule / watt-second) x (3,600 second / hour) =(1,500 x 1,000 x 3,600) x (kilowatt - hour - watt - joule- second) / (kilowatt - watt - second - hour)= 5,400,000,000 joules
What does liters per kilowatt hour mean?
That means kilowatt times hour - a power of 1 kilowatt, over a time of 1 hour, would give one kilowatt-hour. It is, therefore, a unit of energy (equal to 3,600,000 joules, since a joule is a watt-second).
