Fahrenheit to Celsius Converter
Use our Fahrenheit to Celsius converter to convert F to Celsius degrees instantly. Includes the Fahrenheit to Celsius calculator formula, an easy F to C conversion method, examples like Fahrenheit 0 to Celsius, and a conversion chart/table.
What is Fahrenheit to Celsius Conversion?
Fahrenheit to Celsius conversion converts a temperature from the Fahrenheit scale (°F) to the Celsius scale (°C). A fahrenheit to celsius converter is useful for weather, cooking, science, travel, and any time you need a temperature converter chart F to C.
If you’re wondering can fahrenheit be negative, yes—temperatures in Fahrenheit can be negative, just like Celsius. Negative Fahrenheit values are common in very cold climates.
People also ask are fahrenheit and celsius ever the same. Yes—there is one temperature where they match exactly: −40 degrees, where −40°F equals −40°C.
Fahrenheit to Celsius Formula
To convert F to C, subtract 32 and multiply by 5/9. This is the standard f to c conversion equation (fahrenheit to celsius calculator formula).
This is the f to c conversion equation and the main fahrenheit to celsius calculator formula.
Included for reference and reverse conversion.
Use this if you need fahrenheit to celsius and kelvin.
So fahrenheit 0 to celsius is about −17.78°C.
Yes—this is where the two scales meet.

How to Convert F to C
- 1
Enter the temperature in Fahrenheit (°F).
- 2
Subtract 32 from the Fahrenheit value.
- 3
Multiply the result by 5/9 to get Celsius (°C).
- 4
If you also need Kelvin, add 273.15 to the Celsius result.
Frequently Asked Questions
Subtract 32 and multiply by 5/9. The formula is °C = (°F - 32) × 5/9.
Use the exact formula °C = (°F - 32) × 5/9. For a rough easy f to c conversion, subtract 30 and divide by 2 (approximation).
Subtract 32 first, then multiply by 5/9. Doing the order correctly avoids mistakes.
Yes. They’re the same at −40 degrees: −40°F = −40°C.
Yes. Fahrenheit temperatures can be negative, especially in very cold weather.
°C = (°F - 32) × 5/9.
Yes—see the Fahrenheit to Celsius conversion chart above.
Yes. Convert to Celsius first, then add 273.15 to get Kelvin: K = (°F - 32) × 5/9 + 273.15.
