This app calculates the heating time for microwave ovens! It comes in handy when the only cooking times available are for wattages not available on your home microwave, such as for frozen foods or convenience store bento boxes. You can freely enter the wattage, so it’s possible to calculate times for 550W, 720W, etc.

How to Use:
Just enter the wattage and heating time listed on the product, along with the wattage of your home microwave, and press the "Calculate" button.

We offer both a handy iPhone version for quick reference and an iPad version that’s useful while cooking. Please give it a try!
