Key Technical Features
Normalization Strategy: For Length, Weight, and Currency, the code uses a "Base Unit" pattern. It converts the input to a standard (e.g., Meters) and then converts that standard to the target unit. This prevents $N \times N$ complexity in code.
Temperature Formulas: Since temperature doesn't use simple ratios, it uses specific algebraic formulas:
$F = (C \times \frac{9}{5}) + 32$
$K = C + 273.15$
Dynamic UI: Changing a category (like Weight to Temperature) instantly repopulates the dropdown menus without refreshing the page.
Responsive Tabs: The category selector adapts from a 4-column grid on desktop to a 2x2 grid on small mobile screens.
