1 Meter = 3.28084 Feet

How the Math Works

1. ​Standard Units (Length, Weight, Currency): I use a "Base Unit" method. Everything is first converted into a base unit (e.g., Meters or Kilograms) and then multiplied by the target unit's rate.
   • ​Formula: Result = \frac{Value}{Rate_{from}} \times Rate_{to}
2. ​Temperature: This requires specific formulas because it involves offsets (like the +32 in Fahrenheit), not just multiplication.
   • ​Celsius to Fahrenheit: F = C \times \frac{9}{5} + 32
3. ​Responsiveness: The CSS uses a max-width and percentage-based padding so it looks great on iPhones, Androids, and Desktops.

​Implementation Tips

• ​Currency: To make this production-ready, use fetch() inside the setCategory function to grab live rates from an API.
• ​Dark Mode: You can add a @media (prefers-color-scheme: dark) block in CSS to swap the background and card colors automatically.
