How much electricity an electric fan uses in a day depends mainly on the power. The power of ordinary electric fans on the market is generally 40 watts per hour - 150 watts per hour. One kilowatt hour is one kilowatt hour. For example, your electric fan is 100 watts, running a day with the power is:
0.1 kilowatts × 1 hour = 0.1 degrees of electricity, which is one hour of electricity, then a day of electricity is 0.1 degrees × 24 hours = 2.4 degrees of electricity.
If the electric fan is 40 watts/hour, then it uses 0.94 kWh of electricity for 24 hours a day.
If the electric fan is 150 watts/hour, then it uses 3.6 kWh of electricity for 24 hours a day.
Extended information:
The unit of "kilowatt? The unit "kilowatt-hour" is mainly used to measure electricity because "kilowatt-hour" is a more precise unit than the joule. hour" is more easily understood by the general public than the joule, and is more easily converted into hours of electrical use. On the other hand, the joule is more easily converted into hours of electrical use than the kilowatt-hour. On the other hand, Joule is too small a unit of measurement compared to "kWh", making it less convenient to calculate, and there are public ****** organizations in mainland China that use "MWh" instead of "MWh" on their tariffs. hour" instead of "kilowatt-hour". hours" on their tariffs.
Where: 1kW?h = 3,600,000 joules? = 3.6 megajoules (China) = 3.6 megajoules (Taiwan)
A higher unit is the "gigawatt? hour" (GW?h), which describes the amount of electricity generated by a power plant, i.e. 1 GW?h = 3,600,000,000,000 joules = 3.6 Gigajoules (Taiwan). = 3.6?gigajoules (Mainland China) = 3.6?billion joules (Taiwan):.
