# How Much Power Does Microwave Use?

Microwave ovens are being used more and more frequently in our homes, especially as families become busier and meals become quicker and easier to prepare on their own.

However, many people do not realize how much energy these appliances use each year and just how much that affects their power bill at the end of the month.

By understanding this information, you will be able to make the best decision about your next purchase to cut down on unnecessary costs while still enjoying the quick and easy cooking that microwave ovens offer.

The power consumption of microwaves ranges from 800 to 3000 watts, depending on many factors.

The first is wattage, which is generally between 500 and 1,500 watts. Other factors that can significantly affect power consumption are the capacity of the microwave, the item you’re microwaving, cooking time, and container size.

But wattage alone doesn’t tell you how much power your microwave uses. Wattage is only an indicator of heat output, not energy use.

It tells us how much electricity a microwave uses at maximum capacity, but we need to know the other factors to determine how much power will be consumed over time.

For instance, if you cook food for longer or in larger containers, your microwave will use more power.

The amount of time your microwave runs will affect its energy consumption. If you’re only using your microwave for a few minutes daily, it will consume less electricity than if you were using it for an hour each day.

The size of the container affects the power consumption of a microwave. A small container uses less power than a large container.

When you cook something in a small container, you spend less time and power cooking than if you cooked the same food in a large container.

## How to measure microwave power use

A wattmeter is the easiest way to measure a microwave’s power use.

Turn on your microwave and let it warm up for a minute or two (if it doesn’t have an automatic standby mode that shuts off after a certain period, you’ll need to turn it off when you’re done manually).

While it’s running, turn on your wattmeter and watch its reading; after 10 minutes or so, you should see steady voltage readings in watts. If you don’t see a consistent number, try again.

If there are still no numbers, check your wattmeter settings; make sure it’s set to read AC current rather than DC (many meters default to DC) and that it has enough sensitivity to pick up low-voltage AC currents like those produced by microwaves.

## How much power does a 900-watt microwave use?

To calculate how much power a microwave uses, we can use physics to help us out. Many microwaves will specify exactly how much power they use in their operating instructions or packaging.

If you didn’t find your manufacturer’s specifications, two things would be needed to help you determine how much power the microwave uses.

These are the microwave’s wattage and the cooking time; that’s how long something takes to cook in the microwave.

You can usually find the wattage of your microwave by reading the product description in the technical specifications section of the manufacturer’s website.

Amazon might also be a good place to find the wattage of your microwave if it has the type you’re looking for. Check the product description.

In this case, the microwave is 900 watts. You’ll also need to know the cooking time, which is the time it takes to cook something in the microwave.

Let’s assume the item in the microwave takes 30 minutes to cook. Let’s note that in the calculation of power, time should always be in hours.

So you will have to convert your time into hours if it’s not already in the hour unit. So our 30 minutes cooking time is equal to half an hour (0.5 hours) if converted to hours.

**After getting both your microwave wattage and cooking time, you multiply them. So;**

Wattage = 900 watt

Cooking time = 0.5 hour

Power Consumption = Wattage X Cooking time

Power Consumption = 900 X 0.5

Power Consumption = 450

Power consumption should also be kilowatt, so we divide our result or answer by 1000. And we get a final answer of 0.45kWh.

**So in our case, 900 watts microwave with 30 minutes of cooking time uses 0.45 kWh of power.**

## How much power does a 1000-watt microwave use?

To calculate how much power a microwave uses, we can use physics to help us out. Many microwaves will specify how much power they use in their operating instructions or packaging.

If you didn’t find your manufacturer’s specifications, two things would be needed to help you determine how much power the microwave uses.

These are the microwave’s wattage and the cooking time; that’s how long something takes to cook in the microwave.

You can usually find the wattage of your microwave by reading the product description in the technical specifications section of the manufacturer’s website.

Amazon might also be a good place to find the wattage of your microwave if it has the type you’re looking for. Check the product description.

Just like we did with the 900-watt microwave, we will do the same for 1000 watt microwave.

You’ll again need to know the cooking time, which is the time it takes to cook something in the microwave.

Let’s assume the item in the microwave takes 30 minutes to cook. Let’s note that in calculating power, time should always be in hours.

So you will have to convert your time into hours if it’s not already in the hour unit. So our 30 minutes cooking time is equal to half an hour (0.5 hours) if converted to hours.

**After getting both your microwave wattage and cooking time, you multiply them. So;**

Wattage = 1000 watt

Cooking time = 0.5 hour

Power Consumption = Wattage X Cooking time

Power Consumption = 1000 X 0.5

Power Consumption = 500

Power consumption should also be in kilowatt, so we divide our result or answer by 1000. And we get a final answer of 0.50kWh.

**So in the case of 1000 watts microwave with 30 minutes cooking time, 0.50 kWh of power is used.**

## How many volts does a microwave use?

The microwave oven we have at home runs on 110-120 volts. This may not seem like a lot of power, but it actually translates to over 600 watts.

That’s enough energy to light ten ordinary light bulbs at once. In fact, microwaves are so efficient that they use about 0.6% of all electricity produced in America each year.

To put that into perspective, imagine how much power would be required if every microwave in America was running at full capacity 24 hours a day for an entire year.

## Conclusion

Many factors determine how much power a microwave uses, like a microwave’s wattage, capacity, the item you’re microwaving, cooking time, and container size.
