## What is WattCalc?

Stop guessing your microwave heating times! Recalculate any recipe instantly.

Have you ever seen a recipe that says "Heat at 500W for 3 minutes," but your microwave only has a 600W or 800W setting? Don't risk overheating or undercooking your food. WattCalc Microwave is your stylish and precise kitchen utility for perfect results.

Perfect for everyday cooking, recalculating convenience meals (supports up to 1500W), and delicate thawing (200W/300W).

KEY FEATURES:
- Instant Conversion: Easily convert heating times between different microwave wattages (500, 600, 700, 800, 1000, 1500W).
- User-Friendly Design: Sleek, high-contrast dark theme with glowing orange digits, reminiscent of premium kitchen gadgets and classic Nixie tubes.
- Precise Time Input: Add time with +10 Min, +1 Min, +10 Sec buttons.
- Versatile Support: Ranges from high-power 1500W (for convenience store meals) to low-power 200W (for gentle defrosting).
