📚 Technical Background (Optional)

The Fahrenheit and Celsius scales are two widely used temperature measurement systems. The Celsius scale is based on water freezing at 0 °C and boiling at 100 °C under standard atmospheric pressure. The Fahrenheit scale sets water freezing at 32 °F and boiling at 212 °F. The exact conversion formula is °C = (°F − 32) × 5/9. This converter applies this formula instantly, ensuring correct and precise results every time.
