How to convert electric power in kilowatts (kW) to energy in joules (J).
You can calculate joules from kilowatts and seconds, but you can't convert kilowatts to joules since kilowatt and joule units represent different quantities.
To convert electric power in kilowatts (kW) to energy in joules (J), you can use the following formula:
E(J) = 1000 × P(kW) × t(s)
So
joules = 1000 × kilowatts × seconds
or
J = 1000 × kW×s
where
E is the energy in joules,
P is the power in kilowatts,
t is the time period in seconds.
To use the formula, simply substitute the values for P and t into the equation and solve for E.
For example, if you have a power consumption of 4 kilowatts for a time duration of 4 seconds, you can calculate the energy consumption in joules like this:
E(J) = 1000 × 4kW × 4s = 16000J
This means that the energy consumption in the time period is 16000 joules.
It's important to note that the time period must be in seconds to use this formula. If the time period is in a different unit of time, you'll need to convert it to seconds first. For example, if the time period is in hours, you can convert it to seconds by multiplying the number of hours by 3600 (since there are 3600 seconds in 1 hour).
