About this calculator
This calculator helps to calculate the energy consumption of microwaves in watts per minute. The formula used is simple: energy consumed is equal to the power of the appliance (in watts) multiplied by the usage time (in minutes), divided by 60 (to convert minutes to hours) and by 1000 (to convert watts to kilowatts).
The calculator is useful to know exactly how much you are spending with the use of the microwaves in your home. In addition, it can help to compare the consumption of different models of microwaves.
Remember that the energy consumption of microwaves can vary depending on the model and use. Therefore, it is essential to consider other factors when calculating the consumption, such as the efficiency of the appliance and the type of use.
