## Microwave Wattage Formula

The following formula is used to calculate the microwave wattage.

W = V * I

Variables:

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

To calculate the microwave wattage, multiply the voltage by the current. The result will be the wattage of the microwave.

## What is a Microwave Wattage?

Microwave wattage refers to the power level of a microwave oven. It is a measure of how much energy the microwave uses to heat or cook food. The higher the wattage, the more powerful the microwave is and the faster it can cook or heat food. Most microwaves range from 600 to 1200 watts. It’s important to know the wattage of your microwave as many recipes specify a certain power level or cooking time based on the wattage.

## How to Calculate Microwave Wattage?

The following steps outline how to calculate the Microwave Wattage using the formula: W = V * I.

- First, determine the voltage (V) in volts.
- Next, determine the current (I) in amperes.
- Next, gather the formula from above: W = V * I.
- Finally, calculate the Microwave Wattage (W) by multiplying the voltage (V) and current (I).
- After inserting the variables and calculating the result, check your answer with the calculator above.
