Fahrenheit to Celsius Converter
Convert Fahrenheit to Celsius instantly, including common values like 32°F to 0°C, 98.6°F to 37°C, and 212°F to 100°C.
Converted Result
98.6 °F = 37 °C
°C = (°F - 32) × 5 / 9
°F = (°C × 9 / 5) + 32
Water freezes at 32°F (0°C) and boils at 212°F (100°C) at standard atmospheric pressure.

Subtract 32 from the Fahrenheit value
This removes the Fahrenheit freezing-point offset.
Multiply by 5
Scale toward Celsius interval size.
Divide by 9 to get Celsius
Final output in °C.
Worked Example
68°F → (68 - 32) × 5 / 9 = 20°C

The Celsius scale sets water freezing at 0°C and boiling at 100°C.
The Fahrenheit scale sets water freezing at 32°F and boiling at 212°F.
This is why Celsius has 100 intervals between those points, while Fahrenheit has 180 intervals.
(T°C - 0) / 100 = (T°F - 32) / 180
T°C = (T°F - 32) × 5 / 9
We first remove Fahrenheit’s 32-degree offset, then scale by 5/9 because Fahrenheit degrees are smaller.
What is 98.6°F in Celsius?
98.6°F equals 37°C (normal human body temperature baseline).
What is 350°F in Celsius?
350°F equals 176.67°C, a common oven setting.
What is 0°F in Celsius?
0°F equals -17.78°C.
Where are Fahrenheit and Celsius equal?
They are equal at -40 (i.e., -40°F = -40°C).
How do I convert Fahrenheit to Celsius quickly?
Subtract 32, multiply by 5, then divide by 9.
How do I convert Celsius to Fahrenheit?
Multiply by 9/5, then add 32.
Is 100°F considered hot weather?
100°F is about 37.78°C and is generally considered very hot for outdoor conditions.
Why does Fahrenheit start at 32 for freezing?
Fahrenheit uses a different historical scale calibration than Celsius, so freezing and boiling points are offset.
