98.6°F = 37°C

Did you know? Normal body temperature is 37°C.

The average human core temperature, 37°C (98.6°F). It varies slightly by person and time of day.

How to Convert Fahrenheit to Celsius

The formula is:

C = (F − 32) × 5/9

Example: 98.6° Fahrenheit = 37° Celsius

98.6°F equals exactly 37°C — the traditionally cited normal body temperature from Wunderlich's 1868 study. Recent research suggests the true average is closer to 97.9°F (36.6°C), as human body temperature has declined slightly over the past 150 years.

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.
