What temperature is equivalent to 98.9° Fahrenheit?

To convert 98.9° Fahrenheit to Celsius, the formula used is C = (F - 32) × 5/9.

Applying this to our conversion:

1. Subtract 32 from 98.9: 98.9 - 32 = 66.9.

2. Then, multiply by 5/9: 66.9 × 5/9 = 37.2°C.

As a result, 98.9° Fahrenheit is equivalent to 37.2° Celsius. This temperature is significant, as it's typically recognized as a mild fever in clinical practice, helping healthcare professionals assess patient conditions effectively. The other options present temperatures that are either substantially higher than normal human body temperature or do not align with the conversion formula, thus making option A the accurate choice.
