Microwave wattage

Microwave wattage ranges from 600W to 2100W, with 1000W being the most common.
however, the amount of watt that a microwave actually uses is higher than its submit electrical power .
Microwaves use between 841.6W and 2945.8W, with 1402.7W being the most common amount of watts used.
This is based on research into the electrical power of 203 countertop microwaves .
Microwave electrical power and the amount of watt they actually use are unlike because the end product electrical power is different from the remark electrical power .
Let ’ s briefly take a count at this in more detail .

Microwave input vs output wattage 

Microwave input wattage is the amount of watts that the appliance uses. In other words, it ’ s the actual ability consumption of the appliance .
Microwave output wattage refers to the amount of microwave energy made available for heating. Microwave output electrical power is besides known as the cook electrical power .
Microwave output electrical power is the name that ’ s most normally used. This is the electrical power listed in cooking instructions, highlighted most by manufacturers, and referred to in most discussions .
As mentioned, 1000W is the most common microwave wattage (i.e. output wattage). However, the input wattage (i.e. the actual power consumption) of a 1000W microwave is 1402.7W on average.
Microwave remark electrical power is constantly higher than the end product electrical power. This is because microwaves are not 100 % efficient at converting electric department of energy into microwave department of energy .
In saying this, however, microwaves are one of the most energy efficient cooking appliances. Let ’ s take a front at microwave energy efficiency in more detail .

Microwave energy efficiency

Microwaves are 71.29% efficient at converting input power into output power, on average.
In other words : On median, microwaves convert 71.29 % of electricity into microwave cooking office .
For example, a 600W microwave actually consumes 841.6W on average.
Some countertop microwaves are more effective than others .
Modern countertop microwave efficiency can be as low as 54%, in some cases, to 93% and higher in others .
Inverter microwaves are more efficient than conventional microwaves. A samara remainder is that, rather of using a transformer, inverter microwaves offer more master over the magnetron. This enables greater power see, and therefore, offers more efficient heat .
Microwaves in general are the most efficient cooking appliance. Although, there are occasions where ceremonious cook appliances are actually more efficient – more on this in a consequence .
Microwaves are more effective because they cook from the inside out .
side notice : microwaves don’t cook from the center out. The waves reach a depth of approx. 1-2 inches, depending on the world power of the microwave. The estrus created then transfers throughout the food. regular microwaves actually heat particular areas ( around 3-4 inches apart ) of the food, and the areas heated depends on where the food is placed in the microwave. Inverter microwaves, on the other hand, deliver more coherent heating .
As a result, there is less heat and energy wastage from microwaves compared to conventional cook appliances .
convection ovens and ceremonious cookers heat the area surrounding the food, to then cook from the outside in. This is a slower and more inefficient mode of cooking.
In saying this, however, conventional cookers can be a more efficient appliance if you ’ rhenium cooking a lot of food at one meter .
But if you ’ ra cook or reheating a single bowl of food, for model, a microwave is a more effective appliance .
besides, it ’ s worth noting that microwave output electrical power is not a winder energy efficiency factor .
A 700W microwave is not more efficient than a 1200W microwave. It just means that you’ll have to cook the food for longer.
In the end, you ’ ll consume a similar amount of world power when cook .
This of course assumes that both microwaves are exchangeable ( e.g. they ’ re both regular microwaves ) .
Microwaves are becoming increasingly diverse .
many modern microwaves come equipped with a grill / inflame element, which offers more cook versatility while still delivering energy effective heat .
Ultimately, when it comes to energy efficiency, the appliance that has the least amount of energy wastage that also meets your needs tends to be the most energy efficient option.
If a microwave is suitable for you, here ’ s a stand out energy effective model…

As mentioned, some microwaves, particularly inverter microwaves, are more efficient than others at converting input electricity into cooking office .
next, let ’ s take a look at how you can find the manufacturer ’ randomness listed electrical power ( both the stimulation and end product electrical power ) of your microwave .

How to find the wattage of a microwave 

There are several ways to find the electrical power of your microwave .
To find your microwave’s output wattage:

  • Check the plate at the back of your microwave for the listed wattage.
  • Check the inside of the microwave door (or the outside in some cases).
  • Check the owner’s manual.
  • Look online using your microwave’s model number.
  • Estimate the wattage using the “time-to-boil test”.

The “ time-to-boil test ” estimates microwave electrical power from how long it takes your microwave to boil 1 cup of frost cold urine .
Your microwave is 1000W or more if it boils 1 cup of frosting cold urine in less than 2 minutes. It ’ sulfur 800W to less than 1000W if it boils the water in around 2.5 minutes, it ’ south 650W to 700W or higher if it boils in 3 minutes, and finally if it takes more than 3 minutes then your microwave is likely 300W to 500W .
Finding your microwave ’ mho input electrical power is different, but there is some overlap .
To find your microwave’s input wattage (i.e. power consumption):

  • Check the plate at the back of your microwave for input power (i.e. the maximum wattage that the device can use). This will be higher than the output power, which is also listed in watts.
  • Check the owner’s manual. Look for the input wattage figure not the output power figure.
  • Look online using your microwave’s model number. Many online resources don’t make the input wattage easily accessible. You may need to find the owner’s manual online and then search within it to find the power consumption.
  • Estimate the input wattage from the output wattage. On average, microwaves convert 71.29% of their input power into cooking power. So if you know your microwave’s output wattage, you can work out the input wattage yourself or simply use the Microwave Power Consumption Calculator above. However, your microwave may be more or less efficient than average. The next point is the best way to accurately identify your microwave’s actual power consumption.
  • Use a multimeter or energy monitor to see how many watts the microwave is using when it’s running. A smart plug, with an energy monitor feature, may be useful, e.g. the one I use is the KASA smart plug (check it out on Amazon, here.

It ’ mho important to know the input electrical power of a microwave because it gives you a sense of the impact your microwave is having on your electric bills and carbon footprint .
immediately that we know how you can find your microwave ’ south remark electrical power, and since we ’ ve covered how many watts microwaves use on modal, adjacent permit ’ s take a search at how much electricity ( in kWh ) they use. And let ’ s besides put things into perspective by comparing microwave power pulmonary tuberculosis with the might pulmonary tuberculosis of other family appliances .

How much electricity does a microwave use (in kWh)

On average, microwaves consume between .8416 kWh and 2.9458 kWh of electricity per hour, with 1.4027 kWh being the most common.
Based on research into 203 microwaves, 1000W microwaves are the most stocked by retailers in the US .
On average, 1000W microwaves consume 0.0234 kWh of electricity (max) every 1 minute.
But is this a lot ?

Do microwaves use a lot of electricity 

Yes. Microwaves use a lot of electricity.
The listed microwave electrical power tends to be less than ¾ of the sum of electricity that the appliance actually consumes .
For exercise, and angstrom mentioned, a 1000W microwave uses 1402.7W or 1.4027 kWh of electricity per hour, on average .
High powered microwaves use even more electricity, at nearly 3 kWh per hour.
high might microwaves can use more than 3 times the come of electricity compared to low might microwaves .
thus microwaves, peculiarly the senior high school powered models, use a lot of electricity .
Let ’ s get some position by comparing how a lot electricity a microwave uses with the electricity pulmonary tuberculosis of early standard family appliances, and evening a Tesla .
Running a 1000W microwave for 10 minutes is equivalent to:
It ’ second increasingly coarse to find microwaves in homes that have a well higher electrical power than 1000W.

However, despite using a lot of electricity, microwaves are very efficient when it comes to cooking.
As mentioned, it ’ south important to understand the microwave power pulmonary tuberculosis / stimulation electrical power. But it ’ randomness particularly significant to know the output electrical power ( i.e. cooking office ) of your microwave .
This is because cooking instructions give cooking times for specific wattages. Thinking you have a more powerful microwave than you actually have can lead to undercooked food. This is obviously insecure and can lead to illness .
An add problem is that you may need to alter cooking times if your microwave wattage is not the same as what is listed in the cooking instructions .
To help ensure you cook your food appropriately use the Microwave Wattage Conversion Time Calculator below .

Microwave wattage conversion 

When your microwave output electrical power does not match the electrical power listed in the fudge instructions, you need to cook your food for a longer period of time .
This is an increasingly common problem due to microwave wattage becoming more and more diverse.
To help ensure that you cook your food safely, here ’ s how to convert fudge times for microwaves that have different output wattages .
If you don ’ triiodothyronine want to do the mathematics, decamp to the Microwave Wattage Conversion Time Calculator section below .

3 steps to convert microwave cooking times 

  1. Divide the microwave wattage listed in the cooking instructions by your microwave wattage.
  2. Convert the listed cooking time into seconds, if necessary.
  3. Multiply step 1 by step 2.

The result gives you the recommended cook duration, in seconds, for your microwave .
here ’ s the formula :
Your Cooking Time = (Microwave Wattage Listed / Your Microwave Wattage) * Recommended Cooking Time In Seconds
Let ’ s spirit at an model, following the 3 steps and using the formula .
Say you have a 1000 watt microwave and the instructions recommend cooking for 3 minutes in an 800W microwave. here ’ s how you can convert the cook time .

  1. Divide 800 (the wattage listed in the cooking instructions) by 1000 (your microwave wattage). This gives you 0.8.
  2. Convert 3 minutes (the recommended cooking time listed in the instructions) into seconds. The result is 180.
  3. Multiply 0.8 by 180, and you get 144. 

This means that the recommended cooking time for your microwave is 144 seconds or 2 minutes 24 seconds.
here ’ s how it looks in the convention :
Your Cooking Time = (800/1000)*180
not concern in doing the mathematics ? Use the come Microwave Wattage Conversion Time Calculator .

Microwave wattage conversion time calculator

Use the calculator below when your microwave electrical power does not match the microwave electrical power listed in the cook instructions .
This calculator converts recommended cooking times into a cooking time suited to your microwave.
Simply enter the microwave electrical power listed in the cook instructions, your microwave electrical power ( i.e. the end product electrical power / cooking exponent ) and the recommend cook meter .
By default, the calculator is pre-populated, converting a 5 moment ( 300 second ) recommended cooking time for a 900W microwave into the corresponding cook time for a 1250W microwave .
