Microwave Calculator

Adjusts cook time to wattage.


Given cook time and wattage from packaging and the wattage of your microwave, calculates an adjusted cook time.


You can enter arbitrary wattages, but the menus present the most common ones found on actual packaging and microwaves based on my cursory research.

Since times usually don't vary significantly for differences of 100W or less, the 1200W entry of the "actual wattage" menu changes to 900W if you select "1100" as the packaging wattage.

The output time is rounded to the nearest five seconds, but you can alter the "rounding" variable near the head of the script to change this according to your preference.
