Fahrenheit and Celsius conversion
Temperature scales use different zero points and intervals, so the calculator applies the appropriate temperature formula rather than a single multiplication factor.
Conversion example: 25 °F equals -3.8888888889 °C. Enter any temperature above to calculate a precise value for this pair of scales.
This Fahrenheit to Celsius conversion compares two units used to express thermal conditions on different temperature scales. Use Fahrenheit (°F) as the source unit when your original value is recorded in that unit; the calculated result is then presented in Celsius (°C).
