How many watts are in a kWh? Or how do you convert 30 kWh into joules/sec?

Could you possibly give me the formula? I would like to know how to do it (:

1 Kw.h x (1000 watts/Kw) x (60 min/hr) x (60 sec/min) = 3,600,000 J

Note: 1 J/s = 1 watt
1000 watts = 1 KW
1000 watts for 1 hour = 1 KW.h.

To understand the conversion between watts and kilowatt-hours (kWh), it is important to first understand the concepts of power and energy.

Power is the rate at which energy is consumed or produced. It is measured in watts (W), where 1 watt is equal to 1 joule per second (J/s). Power is often used to describe the instantaneous power consumption or production of a device or system.

Energy, on the other hand, is the total amount of work done or heat transferred. It is measured in joules (J). Energy is often used to describe the total amount of power consumed or produced over a period of time.

Now, let's move on to the conversion:

1 kilowatt-hour (kWh) is a unit of energy. It is equal to 1,000 watts multiplied by 1 hour. This can be expressed as:

1 kWh = 1,000 W * 1 hour

To convert energy in kilowatt-hours to power in watts, you need to divide the energy value by the time value in hours. For example, if you have 30 kWh and want to convert it to watts:

30 kWh * 1,000 W/kWh = 30,000 W

So, 30 kWh is equivalent to 30,000 watts.

Now, for the second part of your question, if you want to convert 30 kWh into joules per second (J/s), you need to consider the time aspect. Remember that watts are already equivalent to joules per second. Therefore, to convert 30 kWh to J/s, you can directly convert 30 kWh to watts (using the conversion 1 kWh = 1,000 W) as we did above:

30 kWh * 1,000 W/kWh = 30,000 W

So, 30 kWh is equivalent to 30,000 watts or 30,000 joules per second (J/s).
