This app provides a converter that can calculate the heating time according to the wattage of your microwave oven, or you can also use a chart to quickly check the heating time. The supported wattage ranges from 100W to 3000W in 10-watts increments, and the supported heating time from 10 seconds to 30 minutes. The previously entered values when you close the app are automatically retained, so you don't have to re-enter the wattage you use frequently. *The heating time calculated by this application is only a guide. The actual heating time depends on the model of the microwave oven, the condition of the food or drink, and the difference in wattage between before and after conversion. The developer assumes no responsibility or liability for any problems or damages caused by using this application.
