How to convert from Joules to kW in 1 single step:

How to convert from Joules to kW in 1 single step

Step 1:

It is a very simple conversion, so all you have to do is divide the Joules between time by 1000 which will convert the joules into kW.

Example: An industrial fryer transforms an energy of 420000Joule every 60 seconds, how much power in kW the fryer has. To know the answer you just have to divide 420000 / (1000 × 60), which will result in: 7kW.

Examples of joule to kW conversions:

Example 1:

A gold mine transforms 650000 Joule in just 60 seconds, how many kW does the mine have?

Answer: // The conversion is made easily with the formula that indicates the following: kW = Joule / (1000xseconds), replacing the variables would be: Watts = 650000/60 = 10.83kW

Example 2:

A compactor transforms the energy of 245000 Joules in 240 Seconds, what will be the power in kW of the compactor ?.

Answer: // Keeping in mind the conversion formula we can replace the variables (Joule: 245000, Time: 240 Seconds), being of the following form 245000/1000 × 240 Seconds, the answer would be then: 1.02kW.

Example 3:

An industry transforms an energy of 780000 joules, in 30 seconds, how much will be the power in kW consumed by the industrial process ?.

Answer: // To obtain the answer you must divide the Joules between time by 1000, therefore, using the online calculator, we can obtain a response of 26kW.
