How to Adjust Cooking Time for 700 Watt Microwave

It’s no surprise to overcook or undercook food in a microwave. Unlike cooking on your stovetop, it’s a little fussy to keep on checking on your food while cooking in a microwave.

Think about it, opening the door, checking on your food, closing the door, and pressing start again. This is too much, right? In fact, way more work than simply lifting the lid on your cooking pot.

The biggest problem arises when you try cooking in a microwave with less or more wattage than what’s required to prepare the food in question. Here, it’s very easy to overcook or undercook.

That’s why it’s very important to learn how to adjust your microwave’s cooking time to avoid the hassle.

So, how do you adjust the cooking time for a 700 watts microwave? Let’s find out!

Adjusting Cooking Times for a 700 Watts Microwave

How To Adjust Cooking Time For 700 Watt Microwave

If using a 700 watts microwave for cooking food with a different power rating, you must adjust the cooking time to get the expected results.

Remember, a 700 watts microwave is too slow and may not cook food evenly. Therefore if, for instance, you follow cooking instructions based on a 900 watts microwave and fail to adjust the given cooking time, you’ll be in for a rude shock.

A 700 watts microwave is less powerful than the oven the recipe was initially written for. Therefore, you’ll need more time to get your food to the right temperature.

To boil a cup of water, a 700 watts microwave takes 3 minutes. This information should help you adjust the microwave cooking time/power level to suit the wattage specified in any recipe.

To match a lower wattage

How to Adjust Cooking Time for 700 Watt Microwave

To match 700 watts with a lower wattage, say 600 or 500 watts, you only need to divide the desired wattage by your unit’s wattage.

Then, shift the decimal to 2 places to the right in order to get the percentage power to set the microwave.

Therefore, if following a recipe that calls for 400 watts, you should set the power to 57%. This means that you’ll have to reduce your cooking time to match a lower wattage when using a 700 watts microwave.

To match a higher wattage

To match the power of higher wattage, you need to increase your cooking time when using a 700 watts microwave.

You’ll need to add approximately 10 seconds for every 100 watts. Therefore if a certain food takes 2 minutes in a 900 watts microwave at 100% power, it’ll take 2 minutes and 20 seconds in a 700 watts microwave.

Note that even with the ability to adjust your oven’s cooking time, there are other factors that affect the heating/cooking time of a microwave.

These factors include:

  • The size of the microwave -The bigger the microwave, the more powerful it is and vice versa.
  • Different technologies – Different technologies affect power as well. For instance, convection microwaves blow hot air around your food. This makes it heat more quickly than conventional models. Microwaves with inverter technologies heating even at low power levels. The technology enables the microwave to cook faster than regular models.
  • The amount of food you’re cooking – If cooking a large batch of food at a go in your microwave, it’ll take you more time than when cooking smaller batches.
