The Conversion Formula:
The formula for converting Fahrenheit (°F) to Celsius (°C) is:
C=5÷9 ×(F−32)
Where:
- is the temperature in Fahrenheit.
- is the temperature in Celsius.
This formula works because the Fahrenheit and Celsius scales differ in both their starting point (the freezing point of water) and their scale of measurement.
2. Understanding the Formula:
- The Fahrenheit scale starts at 32°F for the freezing point of water.
- The Celsius scale starts at 0°C for the freezing point of water.
So, the difference between the two scales is 32°F. The number of degrees between each is also different, which is why we multiply by 5/9 to account for the difference in scale size.
3. Applying the Formula to 98.6°F:
Now, let’s use the formula for the specific temperature of 98.6°F.
C=5÷9 ×(F−32)
- Step 1: Subtract 32 from 98.6 to account for the difference in the freezing points of water on both scales.
98.6−32=66.6
- Step 2: Multiply the result by 5/9 to convert the degree difference into Celsius units.
C=5÷9×66.6
C=37
4. Result:
Thus, 98.6°F is equivalent to approximately 37°C.
5. Why This Conversion is Useful:
The temperature of 98.6°F is commonly known as the average normal body temperature in humans. In Celsius, this is around 37°C, which is also considered the typical normal body temperature.
Conclusion:
So, 98.6°F converts to 37°C.
