Automatic Watts to kWh calculator with explanation of formula and main definitions.
In addition to the calculator, it also shows some examples, the main equivalences and the steps for the conversion.
Definitions P (Watts) and kWh:
Kwh = The kilowatt-hour (symbol kWh), is the power in kilo watts multiplied by the time in hours. The kilowatt-hour is commonly used as a power billing unit supplied to consumers by power companies.
P (Watts) = Called active power, it is the power capable of transforming electrical energy into work. The different electrical devices existing convert electrical energy into other forms of energy such as: mechanical, light, thermal, chemical, etc. This power is therefore the actual consumed by the circuits and, consequently, when talking about demand, it is this power that is used to determine such demand.
