Enter the energy in joules and the time in seconds into the calculator to convert the energy to power in kilowatts. This calculator helps in understanding the conversion from a quantity of energy to the rate of energy use or production.
Joules to Kilowatts Formula
The following formula is used to convert energy in joules to power in kilowatts.
P (kW) = E (J) / (t (s) * 1000)
Variables:
- P is the power in kilowatts (kW)
- E is the energy in joules (J)
- t is the time in seconds (s)
To convert joules to kilowatts, divide the energy in joules by the product of the time in seconds and 1000.
What is the Conversion from Joules to Kilowatts?
The conversion from joules to kilowatts is a way to express energy as power. Energy in joules represents a quantity of work done or heat transferred, while power in kilowatts represents the rate at which this energy is used or produced. This conversion is useful in various fields such as electrical engineering, physics, and energy management.
How to Calculate Power from Energy?
The following steps outline how to calculate power from energy.
- First, determine the energy in joules (E).
- Next, determine the time over which the energy is used or produced in seconds (t).
- Use the formula from above = P (kW) = E (J) / (t (s) * 1000).
- Finally, calculate the power in kilowatts (P).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Energy (E) = 5000 joules
Time (t) = 10 seconds
