Lastly, always make sure to follow the manufacturer’s instructions for cleaning and maintaining your microwave oven after use with ceramics as this will help ensure its safe operation for many years to come.

How Hot Does a Microwave Get?

The temperature of a microwave varies depending on its wattage. A typical home microwave oven uses between 500 and 1,200 watts. At this power level, the temperature inside the oven can range from 100 to 250 degrees Celsius (212 to 482 degrees Fahrenheit). Higher wattage microwaves can reach temperatures up to 320 °C (608 °F).

At these temperatures, the food being cooked will heat up quickly and can even begin to cook itself. This is why microwaves are often used to reheat leftovers or prepare frozen meals.
