What is Microwave Wattage?
Wattage is the operating power of electrical equipment. It is expressed in watts.
Microwave wattage is, therefore, the operating power of a microwave. The amount of watts any microwave uses is determined by its volume.
Therefore, the bigger the microwave, the higher the wattage and vice versa.
The Wattage of a Good Microwave
The higher the microwave’s wattage, the better and faster it cooks. A good microwave heats evenly without burning or leaving cold spots in your food.
Microwaves come with various wattage rates, and a 1000 watts unit is the most favorable. It is actually considered as the standard mid-size microwave for even and fast cooking.
That said, note that any microwave with a wattage of 700+ watts can help with all basic microwaving tasks. Therefore, if you have a small family get a 700-1000 watts microwave.
How Many Watts Does a Microwave use?
The number of watts a microwave uses determines how thoroughly and quickly it can cook your food. The higher the wattage, the better your microwave will work.
These appliances come in different wattages, but most come in 600 to 1200 watts.
Bigger units boast higher wattages and are usually more expensive. Compact microwaves have a lower wattage and come at an affordable price.
When selecting a microwave for your home, ensure that the model you go for can help you handle your cooking needs. It should be strong enough to cook your food without wasting too much energy.
The power consumption in microwaves is usually as follows:
600 – 800 Watts
The most compact microwaves on the market usually boast between 600 and 800 watts. They are the cheapest and best for cooking instant foods like noodles, reheating meals and drinks, and heating small foods.
With these microwaves, you’ll spend a long time cooking.
800 – 1000 Watts
Microwaves that fall in this wattage range tend to cook faster and give better cooking results. They are mid-sized and feature a variety of settings that help you cook your food to perfection.
1000 – 1200 Watts
Microwaves that fall within this range are usually very large. They can help you cook enough food for a big family at a go.
They are actually closer to ovens as they heat fast and cook faster as well. Also, most restaurants own microwaves in this range or above.
Determining the Wattage of Your Microwave
Finding the wattage of your microwave is very easy. All you need to do is search the unit on any standard search engine.
Go through the online description or visit the manufacturer’s website to check the detailed technical specification. You might also come across a label with wattage information in your microwave.
To help you get a clear view of different microwave oven capacities and their wattages, we’ve compiled the table below.
The figures may vary from one brand to another.
|0.6 – 0.7 cubic feet||600 – 700 watts|
|0.9 cubic feet||900 watts|
|1.1 cubic feet||1000 watts|
|1.5 cubic feet||1100 watts|
|1.6 cubic feet||1250 watts|
|2.2 cubic feet||1250 watts|
You can also determine the wattage of your microwave using the “time-to-boil” method.
According to this method, a 700W microwave boils a cup of water in 2 minutes 30 seconds. Therefore:
- 2 minutes and 11 seconds = 800 watts
- 1 minute and 57 seconds = 900 watts
- 1 minute and 45 seconds = 1,000 watts
- 1 minute and 20 seconds = 1200 watts
- 1 minute and 10 seconds = 1500 watts
Listed above is the approximate timing of boiling the water. Note the timing might slightly vary depending on the make of the microwave.
The Cost of Running a Microwave
The cost of running a microwave depends on:
- How long the microwave runs
- The wattage of the unit
- Electricity cost in your area
Microwaves with low wattage cook food less quickly and thus cost less to run per minute. However, in some cases, running a stronger microwave that cooks faster might cost you less.
To figure out the cost of running a microwave, you can use this equation:
Kilowatts per hour x $ per kilowatt-hour x time running = cost of running an appliance
To understand this better, consider this example;
There are 1000 watts in a kilowatt. If your microwave is a 900 watts unit, it uses 0.9 kW per hour.
Electricity companies charge per kWh (kilowatt per hour), which is on average $0.12 kWh (12 cents per hour).
Finally, the amount of time a microwave runs dictates how much electricity it uses. If your microwave runs for 2 minutes, that’s 1/30th of an hour.
When you put all these variables into the equation, you’ll get the total cost of running your microwave.
0.9kWh/hour x 0.12 kWh x 1/30th per hour = $0.0037
Running a 900 watts microwave for 2 minutes will cost you $0.0037
