Question

How to calculate the electrical energy consumed?​

Answer 1

1. Calculate Watts Per Day. In this step, simply multiply your device's wattage             by the number of hours you use it in a day.

2. Convert Watt-Hours to Kilowatts. Electricity is measured in kilowatt-hours on your bill, not watt-hours.

3. Find Your Usage Over a Month.  

4. Figure Out the Cost.

Answer 2

Every appliance or electronic device you use is reflected in your monthly energy bill. But, some of those devices are costing you more than others. Do you know which ones? Below, we’ll tell you how to determine and control the energy hogs in your home; just follow these four easy steps:

1. Calculate the watts each device uses per day.  

2. Convert watts to kilowatts. (1 watt = 0.001 kilowatts)  

3. Determine the kilowatts an appliance uses per month.  

4. Figure out the cost. (Some multiplication required.)
