98°F as a body temperature
98°F is 36.67°C, an ordinary body-temperature reading. The often-quoted 98.6°F is exactly 37°C, and the CDC counts a measured 100.4°F (38°C) or more as a fever.
| Reading | °F | °C |
|---|---|---|
| This page | 98°F | 36.67°C |
| Traditional "normal" | 98.6°F | 37°C |
| CDC fever threshold | 100.4°F | 38°C |
- A Celsius thermometer that shows one decimal place reads 98°F as 36.7°C.
- From 98°F to the fever line is 2.4°F but only 1.33°C, because one Celsius degree is 1.8 Fahrenheit degrees.
- This page converts the number only. What a reading means for your health depends on how and where it was taken, so follow the thermometer instructions or a clinician.
- Converting back, 36.67°C × 9/5 + 32 returns 98.0°F, a quick way to check the arithmetic.
The "subtract 30 and halve" trick gives 34°C here, 2.7°C too low, so near body temperature always use (98 − 32) × 5/9.

A quick note before you use the number
Celsius and Fahrenheit use an offset as well as a scale factor, so temperature conversion is not a simple multiplication. Kelvin is handled with the standard absolute-temperature formula.
