Fahrenheit to Celsius Converter
32 degrees Fahrenheit = 0 degrees Celsius
Converting fahrenheit to celsius is a fundamental task in thermal measurement. Daniel Gabriel Fahrenheit developed this scale in 1724, setting 0 as the temperature of a brine solution and 96 as human body temperature (later refined to 98. Today, 1 F equals -17.2222 C, and this conversion is commonly needed in weather forecasting and cooking.
Did you know? Did you know? Daniel Gabriel Fahrenheit developed this scale in 1724, setting 0 as the temperature of a brine solution and 96 as human body temperature (later refined to 98. Meanwhile, the celsius scale was proposed by swedish astronomer anders celsius in 1742, originally inverted (0 for boiling, 100 for freezing). These different origins explain why both units remain in common use today.
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.
