How to Use the Fahrenheit to Celsius Converter
Enter a temperature in degrees Fahrenheit and convert it to Celsius using the standard formula °C = (°F − 32) × 5/9.
Practical Example
For 86°F, subtract 32 to get 54, then multiply by 5/9. The result is 30°C.
Factors That Affect Temperature Interpretation
The conversion formula is exact, but measured temperature can vary with sensor accuracy, calibration, placement, environment and whether the reading represents air, liquid, food or body temperature.
Frequently Asked Questions
What is 32°F in Celsius?
32°F equals 0°C.
What is 212°F in Celsius?
212°F equals 100°C.
Is the Fahrenheit-to-Celsius formula exact?
Yes. The scale relationship is exact; only the original measurement may contain uncertainty.
Conversion Formula and Context
Convert Fahrenheit to Celsius with °C = (°F − 32) × 5/9. For scientific thermodynamic work, Celsius may also need conversion to kelvin because Celsius is not an absolute temperature scale.
