Temperature converter

Degrees Fahrenheit to Degrees Celsius (°F to °C)

Type in either box: it converts both ways, accepts sums like 12*3, and shows every other temperature unit too.

0 °F = −17.77777778 °C. To convert degrees Fahrenheit to degrees Celsius, subtract 32, then multiply by 5/9: °C = (°F − 32) × 5/9.

How to convert degrees Fahrenheit to degrees Celsius

To convert degrees Fahrenheit (°F) to degrees Celsius (°C), subtract 32, then multiply by 5/9.

°C = (°F − 32) × 5/9

Example: 100 °F = 37.77777778 °C.

You can also type 100 °F to °C into the smart calculator, or mix units: 1 °F + 1 °C.

About the units

Degree Fahrenheit (°F)

Water freezes at 32 °F and boils at 212 °F at sea level. Used for everyday temperatures in the US.

Degree Celsius (°C)

Water freezes at 0 °C and boils at 100 °C at sea level. A step of one degree equals one kelvin.

Temperature scales do not share a zero, so converting between them needs an offset as well as a factor. Water freezes at 0 °C, 32 °F and 273.15 K. A change of one degree Celsius equals a change of one kelvin and 1.8 degrees Fahrenheit.
