Temperature conversion is a bit different from other units because it involves starting points (offsets), not just scale factors. The formula isn't as simple as multiplying by a number. The two giants are Celsius (°C), used by almost the entire world, and Fahrenheit (°F), the standard in the United States. Scientists rely on Kelvin (K) for absolute measurements. Whether you're baking a cake, dressing for the weather, or conducting a chemistry experiment, accurate temperature conversion is vital. Remember: Water freezes at 0°C (32°F) and boils at 100°C (212°F).
