The Formulas

How to convert between Fahrenheit and Celsius yourself.

Fahrenheit to Celsius

°C = (°F − 32) × 5⁄9

Example: (72°F − 32) × 5/9 = 22.2°C

Celsius to Fahrenheit

°F = (°C × 9⁄5) + 32

Example: (22°C × 9/5) + 32 = 71.6°F

Fahrenheit vs. Celsius: What's the Difference?

Celsius (°C) is the standard temperature unit used in most of the world. The scale was devised by Swedish astronomer Anders Celsius in 1742 and is based on two reference points: the freezing point of water (0°C) and the boiling point of water (100°C) at standard atmospheric pressure.

Fahrenheit (°F) is primarily used in the United States. Daniel Gabriel Fahrenheit, a physicist born in Gdańsk, introduced this temperature scale in 1724. On the Fahrenheit scale, water freezes at 32°F and boils at 212°F. The 180-degree range between freezing and boiling makes the Fahrenheit scale slightly more granular for everyday use.

Converting between Fahrenheit and Celsius is useful when following American recipes, reading US weather forecasts, or using an oven with Fahrenheit settings. With our free online converter, you can convert any temperature in an instant.

Useful Temperature Facts

Room temperature: A comfortable room temperature of 20–22°C equals 68–72°F. Most thermostats are set around these values.

Body temperature: Normal human body temperature is 37°C, which equals 98.6°F. A temperature above 38°C (100.4°F) is generally considered a fever.

Freezing point: Water freezes at 0°C or 32°F. This is a key reference point in the conversion formula — you always start by subtracting 32 from the Fahrenheit value.

Intersection point: There is exactly one temperature where Fahrenheit and Celsius are equal: −40 degrees. This unique point (−40°F = −40°C) is sometimes used as a mnemonic for remembering the conversion formula.

Frequently Asked Questions

Everything you need to know about converting temperatures.

How do you convert Fahrenheit to Celsius?
Subtract 32 from the Fahrenheit value and multiply the result by 5/9. Example: 100°F → (100 − 32) × 5/9 = 37.78°C. You can also use the free converter at the top of this page for instant results.
How do you convert Celsius to Fahrenheit?
Multiply the Celsius value by 9/5 and add 32. Example: 20°C → (20 × 9/5) + 32 = 68°F.
What is 100 Fahrenheit in Celsius?
100°F equals 37.78°C. This is close to normal body temperature and may indicate a slight fever.
Which countries use Fahrenheit?
The United States, the Bahamas, the Cayman Islands, Liberia, and Palau use Fahrenheit as their primary temperature unit. The rest of the world uses Celsius.
What is the difference between Fahrenheit and Celsius?
Both scales measure temperature but use different reference points. In Celsius, water freezes at 0° and boils at 100°. In Fahrenheit, water freezes at 32° and boils at 212°. One degree Celsius equals 1.8 degrees Fahrenheit.
At what temperature are Fahrenheit and Celsius equal?
At −40 degrees both scales are exactly equal: −40°F = −40°C. This is the only point where the two temperature scales intersect.
How do I convert oven temperature from Fahrenheit to Celsius?
Use the formula °C = (°F − 32) × 5/9, or check the oven table above. Common oven temperatures: 325°F = 163°C, 350°F = 177°C, 375°F = 191°C, 400°F = 204°C and 450°F = 232°C.
What is normal body temperature in Fahrenheit?
Normal body temperature is 37°C, which equals 98.6°F. A temperature above 100.4°F (38°C) is considered a fever.
