Enter the temperature in Fahrenheit and select Celsius as the target unit. The converter uses the formula: C = (F - 32) × 5/9. For example, 32°F = 0°C and 212°F = 100°C.
Kelvin is the SI unit of temperature, used in scientific calculations. To convert from Celsius: K = C + 273.15. To convert from Fahrenheit: K = (F - 32) × 5/9 + 273.15. Absolute zero is 0K (-273.15°C or -459.67°F).
