Difference Between Oven vs Microwave vs OTG

If you have been using or contemplating buying a microwave and confused on which one to opt for. Of course, a Microwave and an Oven are the two most widely used options used for the purpose of cooking. Of course, the two look quite similar ad people tend to get confused between the two. There are several differences between the two. Let us make an attempt at understanding the difference between oven and microwave oven with convection and an OTG.

Difference Between Oven and Microwave?

Well, we will check the differences between the two types of ovens based on a few key parameters.


An oven is a heating element that is used for cooking purposes, and it uses the kinetic induction mechanism. The oven works by heating up the molecules within the air, which travels to the food placed on the oven.

A microwave oven works on the principle of vibration friction that is developed by electromagnetic waves. It uses the microwave to heat food. The microwaves lie between the radio waves and infrared waves and have a frequency range that ranges across 300 MHz to 300 GHz. These can be easily absorbed by the sugar, fat and water.


Conventional or traditional ovens come with metallic elements at the top and bottom. The heating is achieved through the flow of electric current through the metallic elements. The heat thus generated through the energy conversion will cook your food. The oven can even come with a thermostat that controls the temperature by managing the flow of electricity through the metallic elements. Some ovens also have built-in fans that help in distributing the heat in a uniform manner. A standard oven should consume around  1000 to 2000 Watts. However, the power consumption in individual coking sessions will be dependent upon the temperature you have configured through the thermostat.

A microwave oven, on the other hand, works with electromagnetic energy. These ovens generate the electromagnetic waves, and this heats up the whole space inside the appliance where you would be keeping the food items you want to cook. The basic difference between a conventional oven and a microwave would be the way power is used for cooking food in them. A traditional oven heats up the entire space, but a microwave heats up the food alone. That would make a microwave a better option when it comes to efficient power consumption. Ideally, the microwave ovens come with a power rating of around 500 to 1000 Watts.

Cooking Needs

The ovens of both the varieties come with the heating elements. However, They can be used for different cooking purposes. Traditional ovens would be an exceptional option for any type of cooking. It can even work with your needs in baking and browning.

The microwave may not be a good choice for these standard cooking purposes. It does work, but the functionality may not be efficient. However, these are best suited for use with re-heating, roasting and all other types of cooking. The energy consumption is, however, can be a great differentiator between the two. You tend to save at least 75 per cent of electricity with microwaves when compared to the traditional oven.

Major Differences between a Microwave Oven and a Traditional Oven

We thought it would be practical to check out the differences between the oven and a microwave oven in a tabulated manner. This will help you arrive at the exact differences between the two.

FeaturesTraditional OvenMicrowave Oven

Heat DissipationHeat dissipation is quite unevenYou can get an extremely high degree of uniformity in heat dissipation
Temperature controlThere is only a little control over the temperature, and it will be dependent upon the gas usedExtreme control over the temperatures achieved

Difference Between Oven and Microwave with Convection and Standard Microwave?

Now that we have understood the difference between an oven and a microwave, let us try knowing differences between oven and microwave with convection. Microwave ovens come in different types and working principles. The convection microwave is one of the most widely used types of microwaves ovens. How does it differ from the oven or standard microwave oven?

The major difference that puts a convection oven apart from the Microwave is that a microwave with convection feature can be used for baking purposes. A regular microwave may not be able to offer you the best performance in terms of baking and browning activities. A convection oven uses the high-speed fans that circulate dry air around the cooking space.

A microwave, on the other hand, utilises the radio frequency energy for the purpose of heating water and fats. This way, your food will be cooked from the inside rather than being cooked from outside the vessel as in the case of traditional ovens.

difference between oven and microwave with convection

This is exactly an area where you would find that a concept called Convection Microwave makes it quite easy to make use of the advantages offered by both traditional conventional ovens and microwave ovens. This is what combines the best features from both microwave ovens and traditional conventional ovens.

As we are aware, a traditional oven can help you cook new food efficiently,  in addition to letting you use varied cooking practices like baking and browning. A regular or standard microwave will not be able to perform these tasks. It can only be used reheat or roast the food items that have already been cooked. A Convection microwave helps you achieve both applications in one single device. You can make use of convection microwave for cooking those crispy delicacies in the same way you would do on a traditional oven.

The major difference between an oven and a microwave with convection is that the latter can cook anything that you can cook on the former, but will do that faster and in power efficient manner.

However, the microwave oven with convection has a few limitations as well. It will need specific cooking vessels in proper shape, bottom and material of construction. All the utensils you would be using on a traditional oven will not be useful on either a microwave oven or a convection microwave oven.

Difference Between Microwave and OTG

If you are confused about what an OTG is, it is nothing but an Oven Toaster Griller. In fact, it is cooking equipment that can be used as an oven, a toaster and as a griller. It is a compact form of oven and can be used for baking cakes, toasting bread or reheating small amount of food.

The OTG, when compared to the Microwave oven – takes a little more time to cook food. However, when you compare the pricing, you will find that the OTG is cheaper than a microwave oven. From the functionality point of view, though, you will find a microwave oven offering better cooking options than the limited options you have on your OTG. Moreover, opting for a convection microwave oven can further improve your cooking experience by many folds.

The basic differences between a microwave and an OTG can be outlined as here below:

  • The actual technology used in cooking makes a huge difference. An OTG cooks food through the heat generated by the coils and then absorbed by the food. Heat is circulated with the fans, but most of the heat generated is wasted. In case of a microwave oven, the heat is evenly distributed through a rotating plate, and the water molecules inside the food are directly heated.
  • The product you choose will be dependent upon the food you want to cook. Baking cakes, reheating a small amount of food and toasting bread and grilling meat can be the best you can do with an OTG. A microwave can help you do much more than that. If you have a convection microwave, it will even replace your traditional oven.


The basic differences can be found in this table:

FeaturesOTGMicrowave Oven
Time taken to HeatTakes a little time to heat upCan heat up really fast
Power ConsumptionHigherLower
Cooking TimeTakes up a little more time to cookCooks faster
Auto cook menuNot applicableAvailable
VesselsCan use any materialNeeds specific material

Which is Better for Pizza – OTG or Microwave?

Well, if you come to the concept of baking, there is no point in comparing a standard microwave with an OTG. A standard microwave will not be an efficient option for baking purposes. Of course, a convection microwave can ideally replace an OTG to some extent.

Having said that, it should also be remembered that even an OTG may not be a good option for making Pizza. The OTG will come with smaller capacity, and it may not function well enough with a Pizza preparation you have been planning. If you ask us, we would recommend opting for a small oven – larger enough than the OTG.

However, if you want to know which is better for pizza- OTG or Microwave, a microwave is a strict no-no for cooking pizza, cakes or even cookies. Even an OTG may not be adequate for most of your requirements in baking cakes. We would definitely recommend you opt for a larger convection microwave oven.

How much Electricity does Microwave use?

Well, you would definitely want to know OTG v/s Microwave power consumption. However, finding it will need to take consideration into some major factors as we have outlined here below:

  • Check out the wattage of your microwave oven. These ovens come with a wattage of around 600 to 1200 Watts. Commercial grade microwave ovens come with a wattage value of around 1800 Watts.
  • It should be noted that the microwave does not run always at its rated wattage. There are several low power settings, and it will tend to run at the lower wattages than those specified.
  • OTG consumes much higher power than that if microwave oven.


How many amps does a microwave use? Well, no microwave shares the exact amperage that it uses. However, you should be able to calculate it easily. Please note that the actual amperage will be dependent upon the exact voltage at your place.

Use the following formula for arriving at the exact amperage value –

Current = Power in watts / the voltage in volts.

If your microwave oven comes with a wattage of 1200 Watts and the local voltage in your area reads 230 V, you will find that the microwave in question consumes 5.2 Amps of current.

How Many Watts does a Microwave use?

We just had a comparison between the OTG and Microwave Oven in the previous sections of this post. But, how many watts does a microwave or an OTG use?

An average microwave oven consumes around 600 to 800 Watts. The same figure for an OTG is around 1200 Watts. This will indicate that the microwave oven is one of the best options to go with when compared to the OTG in terms of power consumption. The actual differences between the two will be dependent upon the actual wattage that your OTG and microwave oven has. However, in any case, Microwave ovens have been one of the excellent options in comparison to the OTGs if you are looking at power consumption.

What size Microwave fits a Dinner Plate?

Microwave ovens come with different sizes. It should also be noticed that dinner plates also come in multiple sizes. So, ideally speaking – there is no specific size of a microwave that would fit a dinner plate perfectly.

However, assuming that an average dinner plate comes in a size of around 12 inches, we would assume that microwave of the mid-range should ideally be the best you would want to go with the 12-inch plate. In fact, even some of the compact models of microwave ovens can handle the 11 or 12 inches dinner plates.

However, if you are looking to fit in a larger plates – or the cake plates that can measure above 13 inches in diameter, you would need to opt for the larger size of the microwave oven.

The Concluding Thoughts

Those were a few tips that should help you make the right choice between an oven and a microwave oven. We assume that the various differentiations that we have been able to arrive in the above discussion should be helpful enough in arriving at the best experience in terms of microwave ovens and other similar products.
