Joules are used to measure energy. Also the related concept of work, which can be thought of as the transfer of energy.
Joule is the unit used to measure energy.
The answer is Temperature
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.
You can't determine the amount of wavelength that equals 5 joules. Wavelength measures the length of the period while joules measure energy.
E= hf = hc/r in Joules.
joules or kilo-joules

All energy is measured in joules.
Joule is the unit used to measure energy.
Joules are the metric units used to measure energy. When you are working with any form of energy you state them in joules.
Energy of heat = Joules (J)
Kilo joules are used to measure the amount of energy stored in food.
The unit used for ANY type of energy is the joule.
Joules
231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules.
