What is 37 degrees Celsius in Fahrenheit?

37 degrees Celsius equals 98.6 degrees Fahrenheit. The conversion uses the formula Fahrenheit = (Celsius × 9/5) + 32, so 37 × 9/5 = 66.6, and 66.6 + 32 = 98.6°F.

This temperature is famous because 37°C was traditionally taught as the average normal human body temperature. In reality, healthy body temperature varies between people and changes during the day, with activity, age, measurement method, and location affecting the reading.

The Celsius and Fahrenheit scales have different historical origins. Celsius was developed in the 18th century and defines the freezing and boiling points of water at 0°C and 100°C under standard atmospheric pressure. Fahrenheit uses a different scale, with water freezing at 32°F and boiling at 212°F under the same conditions.

A common mistake is to assume that every reading of 37°C means a fever. Medical interpretation depends on how the temperature was measured and on the person’s symptoms. The conversion itself, however, is exact: 37°C is 98.6°F.
