About Fahrenheit to Celsius
Convert fahrenheit to celsius instantly, with a reference table of common values. Because the two scales do not share a zero point, this needs a formula rather than a single multiplier โ the converter applies the exact fahrenheit-to-celsius conversion for you.
What Americans need abroad, and what anyone needs to interpret a US weather report or recipe. The quick mental approximation โ subtract 30 and halve โ is close enough for weather but not for cooking.
Daniel Fahrenheit devised his scale in 1724, setting 0 at the freezing point of a brine solution and 96 at approximate body temperature. Later refinement shifted body temperature to 98.6, which is why the numbers look arbitrary โ they are the residue of a calibration that was itself adjusted. It remains the everyday scale in the United States and a few smaller territories, and persists in older British and Caribbean usage for weather. Water freezes at 32 ยฐF and boils at 212 ยฐF, and a comfortable room is about 70 ยฐF.
Worked through with real numbers: -10 ยฐF is -23.333 ยฐC, 0 ยฐF is -17.778 ยฐC, 20 ยฐF is -6.667 ยฐC, 100 ยฐF is 37.778 ยฐC.
As for the other side of the conversion: water freezes at 0 ยฐC and boils at 100 ยฐC at sea level, and normal human body temperature is about 37 ยฐC.
Temperature is the one conversion here that needs a formula rather than a single factor, because Celsius and Fahrenheit do not share a zero point. That offset also means a temperature difference converts differently from a temperature: a rise of 10 ยฐC is a rise of 18 ยฐF, not 50 ยฐF.

Frequently asked questions
How do I convert fahrenheit to celsius?
Enter a value above and the exact celsius temperature appears instantly, using the standard fahrenheit-to-celsius formula.
When would I need to convert fahrenheit to celsius?
What Americans need abroad, and what anyone needs to interpret a US weather report or recipe. The quick mental approximation โ subtract 30 and halve โ is close enough for weather but not for cooking.
What is a fahrenheit, exactly?
Daniel Fahrenheit devised his scale in 1724, setting 0 at the freezing point of a brine solution and 96 at approximate body temperature. Later refinement shifted body temperature to 98.6, which is why the numbers look arbitrary โ they are the residue of a calibration that was itself adjusted. Water freezes at 32 ยฐF and boils at 212 ยฐF, and a comfortable room is about 70 ยฐF.
Where is the celsiu actually used?
It is the everyday temperature scale in almost every country, and the scientific standard for ordinary laboratory work. Water freezes at 0 ยฐC and boils at 100 ยฐC at sea level, and normal human body temperature is about 37 ยฐC.
Is there anything tricky about temperature conversions?
Temperature is the one conversion here that needs a formula rather than a single factor, because Celsius and Fahrenheit do not share a zero point. That offset also means a temperature difference converts differently from a temperature: a rise of 10 ยฐC is a rise of 18 ยฐF, not 50 ยฐF.
Is this converter accurate?
Yes. It applies the standard scale conversion exactly, with no rounding beyond what is shown.
