Use this page when you want a direct Fahrenheit to Celsius conversion. On this page, 1 Fahrenheit equals -17.222222 Celsius.
The direct answer, calculator, common values table, and FAQ all follow the same exact equation for this route: C = (F - 32) x 5/9.
Fahrenheit (deg F): a temperature scale used mainly in the United States for weather, cooking, and household references.
Celsius (deg C): a relative temperature scale widely used in weather, science, and everyday measurement.
This route is useful for weather, cooking, HVAC, travel, and international references where fahrenheit and celsius describe the same physical temperature on different scales.
This conversion uses an affine temperature equation with scale and/or offset terms, so forward and reverse pages must use inverse formulas rather than one shared factor.
