Our microwave power time conversion table will help you solve the problem of microwave cooking instructions not matching the power rating of your microwave oven. Microwave power timing conversion is an important aspect of microwave cooking because if your microwave’s power rating is different from the microwave power rating that the cooking instructions are based on you will end up either overcooking or under cooking your food.
For example, if you follow a microwave recipe or cooking instructions based on a 900 Watt oven but you have a microwave which is rated at only 700 Watts, an instruction saying cook for 10 minutes will not be long enough for your oven and will therefore leave your food undercooked. This is because your 700 Watt oven is less powerful than the oven the recipe was written for and will need more time to get the food to the correct temperature. Luckily for you, I have provided everything you need to make sure that you can easily convert a timing from any recipe and set the cooking time which is correct for your microwave. Just follow the 3 steps below and use the quick Microwave Power Time Conversion lookup table to find out how much time you should set your microwave oven timer to to cook your food properly.
1. Find out the power rating of your microwave
Your microwave will have a certain power rating in Watts(W). Mine for example is a 900W oven. Finding out the power rating should be easy.
Some microwaves have a helpful label on the door to let you know it’s power as shown below. Just take a note of the number at the top right which is 900W in this case. Ignore the E which is the heating category as this just confuses things.
If there is no label on the front of your microwave, look for a label inside the or at the the back. It may not look like the one pictured above but as long as it has the power in Watts / W you’ll be fine.
If you can’t find it on the oven itself check the manual.
2. Note the power used for the microwave recipe or packaging.
All cooking times for the recipes in this site are based on a 900W microwave oven. Other microwave recipe sites should tell you what power theirs are based on. Packaged food such as a tin of baked beans and microwave dishes such as ready meals should indicate what microwave power the cooking times are based on. If the cooking / heating instruction timings are based on the same microwave power rating as yours then you can simply use the timings given an enjoy your food. If they are different then go to step 3.
3. Use the Microwave Power Time Conversion table to find the correct time for your oven.
So, if your microwave power rating is not the same as the microwave power given by the recipe or heating instructions use the Microwave Power Time Conversion Table below. All you need to do is
- In the top row of the table find the power rating specified by the microwave recipe or cooking instructions e.g. 750W
- Go down until you find the cooking time given by the cooking instructions (to the nearest 10 secs) e.g. 3:00
- Go across until you get to the column which has your microwave oven’s power rating at the top e.g. 900W and you have found the cooking time you need for your microwave which is this example is 2:30.
- Set your microwave to the time found in the table and enjoy your food.
|Microwave Power Time Conversion Table|
|1500 W||1250 W||1100 W||1000 W||950 W||900 W||850 W||800 W||750 W||700 W||600 W||500 W|
Note 1. You will notice that the microwave power time conversion table rounds timings to the nearest 10 seconds. We’ve done this because a time difference within 10 seconds will not usually make much difference to how well your food is cooked.
