fahrenheit to celsius
Convert °F to °C for travel, science notes, and metric forms.
To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9. In symbols, °C = (°F - 32) × 5/9. This free fahrenheit to celsius converter runs that formula for you. Use it when a US weather, oven, or body-temperature reading must be stated in Celsius. Travel apps, lab notes, and overseas forecasts are common reasons to convert a US reading.
How to convert fahrenheit to celsius
Use °C = (°F - 32) × 5/9. Subtract 32 from Fahrenheit, then multiply by 5/9.
Example: (68 - 32) × 5/9 = 20. So 68°F equals 20°C.
Order matters. Subtract 32 first, then multiply. Room targets like 68°F and 72°F convert cleanly for travel thermostats.

Common Fahrenheit to Celsius conversions
32°F is 0°C. 212°F is 100°C. Those are the freezing and boiling anchors.
68°F is 20°C. 72°F is 22.22°C, a common indoor comfort range in US homes.
98.6°F is 37°C. 100.4°F is 38°C, a fever checkpoint on many household charts.
Write both units when you share a reading with mixed audiences. That habit prevents a second conversion later.
Why Celsius still appears beside US Fahrenheit
US daily life is still full of Fahrenheit numbers. Science class, travel apps, and much of the world report the same conditions in Celsius.
A fahrenheit to celsius conversion keeps your original US reading while matching metric reports. It is useful for weather abroad, recipes, and health notes.
When a recipe lists a candy stage in Fahrenheit, convert carefully. Small degree errors change texture results.
US school and clinic notes may still use Fahrenheit. Convert when a form expects Celsius only.
A heat advisory near 100°F is about 37.78°C. That helps when reading mixed sources.
When a recipe lists a candy stage in Fahrenheit, convert carefully. Small degree errors change results.
Keep the formula handy: subtract 32, then multiply by 5/9 for any Fahrenheit reading.
Share both units with mixed audiences so nobody has to convert your number again.
Frequently asked questions
What is 72°F in Celsius?
72°F equals 22.22°C.
