  • The usage can differ from one household to another. It also depends on the capacity of the oven. However, the more you use the microwave oven, the higher is the consumption.
  • Microwave ovens come with a range of power ratings. Like the LG convection microwave listed above, those with advanced features have a higher power rated value of 1950W, whereas the IFB convection oven has a lower rating. The ovens with a higher power rating consume more power.
  • The electricity tariff can vary from one place to another. Therefore, depending on where you reside, you can input the figure accordingly.

Frequently Asked Questions

What does the rated power of the appliance signify?
The ‘Rated Power of the Appliance’ signifies the amount of power it consumes during its operation. This figure is generally in watt.
How do you calculate the units consumption?
The specification sheets list the rated power of the appliance in watts. You divide the figure by 1000, and you get the figure in Kilowatts. For example, the Samsung convection oven has a rated power of 1400W. It amounts to 1.4 kW. This unit consumes 1.4 kW of power in an hour. That gives you the power consumption in units.
