Converting between Celsius and Fahrenheit is essential for international travel, cooking, weather forecasting, and scientific applications. Celsius is used worldwide and is part of the metric system, while Fahrenheit is primarily used in the United States. The conversion formula is F = (C × 9/5) + 32, where water freezes at 0°C (32°F) and boils at 100°C (212°F) at standard atmospheric pressure.

Common Temperature Reference Points
- Water freezes: 0°C = 32°F = 273.15K
- Water boils: 100°C = 212°F = 373.15K
- Room temperature: ~20°C = ~68°F = ~293K
- Body temperature: 37°C = 98.6°F = 310K
- Absolute zero: -273.15°C = -459.67°F = 0K
