Enter the voltage and current into the calculator to determine the oven wattage. This calculator can also evaluate any of the variables given the others are known.

Oven Wattage Formula

The following formula is used to calculate the oven wattage.

W = V * I


  • W is the wattage (Watts) V is the voltage (Volts) I is the current (Amperes)

To calculate the oven wattage, multiply the voltage by the current. The result will be the wattage, which is the amount of power the oven uses.

What is an Oven Wattage?

Oven wattage refers to the amount of electrical power an oven uses to operate. It is measured in watts and is usually listed in the product specifications. The higher the wattage, the more power the oven uses, which typically means it can heat up faster and maintain higher temperatures. However, a higher wattage also means the oven will consume more electricity, which could lead to higher energy bills.

How to Calculate Oven Wattage?

The following steps outline how to calculate the Oven Wattage.

  1. First, determine the voltage (V) in volts.
  2. Next, determine the current (I) in amperes.
  3. Next, gather the formula from above: W = V * I.
  4. Finally, calculate the Oven Wattage (W).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

voltage (V) = 120 volts

current (I) = 5 amperes
