98.5 degrees Fahrenheit equals approximately 36.94 degrees Celsius.
Converting 98.5°F to Celsius requires subtracting 32 then multiplying by 5/9. This adjusts the Fahrenheit scale which starts at a different freezing point than Celsius, allowing us to find the equivalent temperature in Celsius.

Conversion Formula
The formula for converting Fahrenheit (F) to Celsius (C) is:
C = (F – 32) × 5/9
This formula works because the Fahrenheit scale sets the freezing point of water at 32 degrees and boiling at 212 degrees, while Celsius sets freezing at 0 and boiling at 100. Subtracting 32 removes the offset, then multiplying by 5/9 scales the difference to Celsius degrees.
Example calculation for 98.5°F:
- Subtract 32: 98.5 – 32 = 66.5
- Multiply by 5/9: 66.5 × 5/9 = 36.94°C
Conversion Example
- Convert 120°F:
- Subtract 32: 120 – 32 = 88
- Multiply by 5/9: 88 × 5/9 ≈ 48.89°C
- Convert 45°F:
- Subtract 32: 45 – 32 = 13
- Multiply by 5/9: 13 × 5/9 ≈ 7.22°C
- Convert 0°F:
- Subtract 32: 0 – 32 = -32
- Multiply by 5/9: -32 × 5/9 ≈ -17.78°C
- Convert 212°F:
- Subtract 32: 212 – 32 = 180
- Multiply by 5/9: 180 × 5/9 = 100°C

Conversion Definitions
Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It was created by Daniel Gabriel Fahrenheit in the early 18th century and is mainly used in the United States and a few other countries.
Celsius: Celsius is a metric temperature scale where zero represents the freezing point of water and 100 the boiling point at sea level. Proposed by Anders Celsius, it’s widely adopted around the world for scientific and everyday measurements of temperature.
Conversion FAQs
Why do I subtract 32 when converting Fahrenheit to Celsius?
You subtract 32 because the Fahrenheit scale sets the freezing point of water at 32 degrees, unlike Celsius which sets it at zero. Removing 32 aligns the starting points, so the remaining temperature difference can be scaled properly.
Can I convert Celsius back to Fahrenheit easily?
Yes, the reverse formula is F = (C × 9/5) + 32. Multiply the Celsius temperature by 9/5 and then add 32 to get the Fahrenheit equivalent.
Is the conversion formula exact for all temperatures?
The formula provides a mathematically exact conversion between Fahrenheit and Celsius scales for any numeric temperature, because both scales are linear. However, real-world temperature measurements may include slight variations from instruments.
Why is 98.5°F close to 37°C considered normal body temperature?
The average human body temperature is around 98.6°F, or 37°C, which is the temperature where many bodily processes function optimally. Slight differences like 98.5°F still fall within the normal physiological range.
Does altitude affect the Fahrenheit to Celsius conversion?
No, altitude does not affect the mathematical conversion between Fahrenheit and Celsius. However, altitude can influence actual temperature readings due to atmospheric pressure changes, but the formula remains the same.
