The Microwave Calculator

The Microwave Calculator

Microwave cooking instructions on food packaging often don’t match your microwave’s power settings, making it hard to know how long to cook your food. This microwave power and cooking time converter helps you adjust cooking times accurately based on your microwave’s wattage.

Whether you're using a 700W, 800W, 900W, or 1000W microwave, this tool gives you precise cooking times without the guesswork. It’s designed to be fast, mobile-friendly, and easy to use — perfect for quick access in the kitchen. It even has a timer function.

If you want better microwave cooking results, avoid undercooked meals, and save time, this microwave calculator is for you.

Generally it is better to microwave at a lower power and for longer - try that in the calculator!

How to Use It:

1. Set Packaging Instructions: Use the +/− buttons to match the power and time shown on your food packaging.
2. Set Your Microwave Power: Adjust to match your microwave's power setting (shown on your dial or display).
3. View Adjusted Time: The timer automatically calculates the correct cooking time to use for your microwave.
4. Start Timer: If you want to use the timer here press "Start" to begin the countdown. Use +30/−30 or Pause to adjust the time while running.

Caution: If the timer shows orange or red, you're cooking much faster than recommended. Always check food frequently to ensure even heating.

Your microwave power setting is saved automatically for next time.
