The conversion from kilowatts (kW) to kilowatt-hours (kWh) involves understanding the relationship between power and energy over time.
Definitions
- Kilowatt (kW) :- A unit of power equal to 1,000 watts. It represents the rate at which energy is used or generated. kilowatts measures power (instantaneous rate of energy use
- Kilowatt-hour (kWh) :- A unit of energy equivalent to one kilowatt of power used for one hour. It represents the total amount of energy consumed or produced. kilowatt-hour measures energy (total power used over time).
The conversion formula helps quantify energy consumption based on the power rating of a device and the duration of its usage.
Relationship
To convert kW to kWh, you multiply the power (in kW) by the amount of time (in hours) the power is used.
General Formula
\[ W = P \times t \]Unit of Measurement:
-\(W\) : The energy consumption in kilowatt-hours (kWh).
-\(P\) : The active power rating of the device in kilowatts (kW).
-\(t\) : The total usages time on device is used, usually measured in hours (h).
Practical Examples
If you have an electrical appliance that operates at 2 kW and you use it for 3 hours, the energy consumed is:
\[ W = 2kW \times 3h = 6 kWh \]Therefore, the energy consumption is 6 kWh
