How It Works
Converting Fahrenheit to Celsius reverses the two differences between the scales. The converter first subtracts 32 to realign the freezing point of water to zero, then multiplies by 5/9 to resize the degrees to the Celsius scale. It also returns Kelvin by adding 273.15 to the Celsius result, giving you the everyday and scientific scales side by side from a single Fahrenheit reading.
Formula
°C = (°F − 32) × 5/9
Examples
Convert 68°F
68°F (room temperature) equals 20°C.
