How to calculate power consumption of appliances. 480 1000 48 kWh per day. Actual wattage of products varies depending on product age and features. Incandescent light bulb with a power of 60 watts.

The number of days per year when the appliance is in use. KW Tumble drye rs stovesovens 35-40kW. To calculate power consumption you must know that the consumed electricity depends mostly on two factors-Wattage of the appliance.

To calculate the current consumption you need to know its strength as well as the voltage of the source. These figures are approximate representations and the actual power consumption of your appliances may vary substantially from these figures. It can help you find the basic number of hours and watts that are being consumed on a regular basis.

One kilowatt is equal to 1000 watts so to calculate how many kWh a device uses divide the watt-hours from the previous step by 1000. Energy Use Calculator offers electricity usage calculators for various devices. By mutiplying these two factors we can get the theoritical power consumption by the appliance.

What is its size type time in use and the technology of the device etc. Since were calculating the energy consumption over a month youll want to multiply the kWh per day by 30. Next divide the watt-hours per day by 1000 to convert it into kilowatt hours per day or kWh per day.

Calculate the annual use. Then start using the appliance and you can see in real time how many kWh units of electricity the appliance is using. For this you need to take into account the power factor.
