Fahrenheit to Celsius Converter
32 degrees Fahrenheit = 0 degrees Celsius
Conversion formula
C = (F - 32) x 5/9
To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9 (or divide by 1.8). This reverses the Celsius-to-Fahrenheit formula.

About Fahrenheit to Celsius
Converting Fahrenheit to Celsius is essential for Americans traveling abroad, reading international weather reports, or following European recipes. The formula C = (F - 32) x 5/9 reverses the more commonly known Celsius-to-Fahrenheit conversion.
Important reference points: 32 F is freezing (0 C). 72 F is a comfortable room temperature (22.2 C). Body temperature of 98.6 F is 37 C. Water boils at 212 F (100 C). An oven set to 350 F is 176.7 C.
Weather context makes this practical: if you're checking the weather in London and see 15 C, you know that's 59 F - pleasant but cool. Paris in summer at 28 C means 82.4 F. Sydney reporting 40 C is a scorching 104 F.
For cooking, common American oven temperatures translate as: 325 F = 162.8 C, 350 F = 176.7 C, 375 F = 190.6 C, 400 F = 204.4 C, and 425 F = 218.3 C. European ovens are calibrated in Celsius, so American expats need these conversions daily.
Medical thermometers in most countries display Celsius. An American reading 38.5 C might not realize that's 101.3 F - a significant fever. At 40 C (104 F), seek medical attention immediately.
Quick mental shortcut: subtract 30 and halve the result. So 80 F becomes (80 - 30) / 2 = 25 C (actual: 26.7 C).
Frequently Asked Questions
What is 72 Fahrenheit in Celsius?
72 F equals 22.2 C. This is considered a comfortable room temperature in the United States.
What is the formula to convert F to C?
C = (F - 32) x 5/9. First subtract 32 from the Fahrenheit temperature, then multiply by 5/9 (or 0.5556).
What is 350 F in Celsius for baking?
350 F equals 176.7 C. Most European oven recipes round this to 180 C, which is one of the most common baking temperatures.
Is 100 F a fever?
100 F (37.8 C) is considered a low-grade fever. Normal body temperature is 98.6 F (37 C). Most doctors consider 100.4 F (38 C) and above to be a true fever.
