Enter the energy in kilojoules and the time in seconds into the calculator to convert the energy to power in kilowatts. This calculator helps in understanding the conversion from energy (KJ) to power (KW).

KJ to KW Conversion Formula

The following formula is used to convert energy in kilojoules (KJ) to power in kilowatts (KW).

P (KW) = E (KJ) / t (s)

Variables:

  • P is the power in kilowatts (KW)
  • E is the energy in kilojoules (KJ)
  • t is the time in seconds (s)

To convert energy to power, divide the energy value in kilojoules by the time in seconds. The result will be the power in kilowatts.

What is the Difference Between Energy and Power?

Energy and power are closely related but are not the same. Energy is the total work done or heat generated when a force moves an object over a distance, while power is the rate at which this energy is used or transferred. In other words, power is the rate of doing work or using energy. Energy is measured in joules (J) or kilojoules (KJ), and power is measured in watts (W) or kilowatts (KW).

How to Use the KJ to KW Calculator?

The following steps outline how to use the KJ to KW Calculator.


  1. First, enter the energy in kilojoules (E).
  2. Next, enter the time in seconds (t).
  3. Use the formula P (KW) = E (KJ) / t (s) to calculate the power.
  4. Finally, the calculator will display the power in kilowatts (KW).
  5. Use the reset button to clear all fields and perform a new calculation.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Energy (E) = 5000 kilojoules

Time (t) = 100 seconds
