How to Convert Fahrenheit to Celsius

The formula is:

C = (F − 32) × 5/9

Example: 99° Fahrenheit = 37.222° Celsius

99°F equals 37.2°C — slightly above the traditional normal of 98.6°F. Generally not classified as a fever in adults, but may indicate the body is responding to an infection or inflammation.

About these units

Fahrenheit: The degree Fahrenheit (°F) is a temperature unit in the US customary system. On this scale, the freezing point of water is 32 °F and the boiling point is 212 °F — exactly 180 degrees apart. ...

Celsius: The degree Celsius (°C) is the SI-derived unit of temperature. It is defined so that 0 °C = 273.15 K exactly, with the same unit increment as the kelvin.
