What Is Fahrenheit to Celsius Conversion?
Fahrenheit to Celsius conversion is the process of changing a temperature value from the Fahrenheit scale (°F) to the Celsius scale (°C). Fahrenheit is primarily used in the United States, while Celsius is used in most other countries and in scientific contexts worldwide.
The two scales have different starting points and different degrees per unit. Water freezes at 32°F (0°C) and boils at 212°F (100°C). Between those two points, Fahrenheit has 180 degrees while Celsius has 100 — that’s why the conversion isn’t a simple multiplication.
The Formula
The formula to convert Fahrenheit to Celsius is:
Step-by-Step Example
Let’s convert 98.6°F (normal body temperature) to Celsius:
- Start with: °C = (98.6 − 32) × 5/9
- Subtract 32: 66.6 × 5/9
- Multiply by 5: 333 / 9
- Divide by 9: 37 °C

❓ Frequently Asked Questions
What is the formula to convert Fahrenheit to Celsius?
The formula is: °C = (°F − 32) × 5/9. First subtract 32 from the Fahrenheit value, then multiply by 5, then divide by 9.
Is this Fahrenheit to Celsius converter free?
Yes, our converter is 100% free with no signup, no download, and no usage limits.
At what temperature are Fahrenheit and Celsius the same?
At -40 degrees! -40°F = -40°C. This is the only point where both scales show the same number.
What is 98.6°F in Celsius?
98.6°F is 37°C — the normal human body temperature. This is one of the most common conversions in medicine.
What is 32°F in Celsius?
32°F is exactly 0°C — the freezing point of water at standard atmospheric pressure.
What is 212°F in Celsius?
212°F is 100°C — the boiling point of water at sea level.
Why is Fahrenheit still used?
The United States, Bahamas, Cayman Islands, Palau, and a few other countries still use Fahrenheit for everyday temperature. In most other places, Celsius is the standard.
How do I convert Celsius to Fahrenheit?
Use the reverse formula: °F = (°C × 9/5) + 32. We also have a dedicated Celsius to Fahrenheit converter on our tools page.
Does it also show Kelvin?
Yes! Our tool displays all three temperature scales — Fahrenheit, Celsius, and Kelvin — so you have complete information at a glance.
