Fahrenheit To Celsius
Convert Fahrenheit (°F) to Celsius (°C) instantly with this free online temperature converter. Enter any Fahrenheit value for the exact Celsius equivalent using the (F − 32) × 5/9 formula for cooking, weather, science, and everyday use.
About This Calculator
The Fahrenheit to Celsius Converter is a free online tool that instantly converts temperatures from Fahrenheit (°F) to Celsius (°C). Whether you are following an American recipe that lists oven temperatures in Fahrenheit, checking a US weather forecast, or working on a science experiment that requires metric temperature readings, this calculator provides instant and accurate conversions for all your needs.
The conversion follows the standard formula: °C = (°F − 32) × 5/9. Subtract 32 from the Fahrenheit value, multiply the result by 5, then divide by 9. For example, 212°F (the boiling point of water) converts to 100°C: (212 − 32) = 180, then 180 × 5/9 = 100°C. Our calculator handles all values, including negative temperatures and decimal values, with precise results rounded to two decimal places.
Regional Notes
United States: Fahrenheit is the standard scale for weather forecasts, cooking, and body temperature measurements. Common conversions include 98.6°F (normal body temp) = 37°C, and 350°F (common baking temperature) = 176.67°C.
United Kingdom: The UK uses Celsius for most official weather reports but Fahrenheit is still understood by older generations and occasionally appears in some newspapers. Many UK ovens display temperatures in both Celsius and Fahrenheit.
India: India uses Celsius exclusively for weather, cooking, and all scientific work. Travelers from the US visiting India may find this converter useful for understanding local temperature reports.
Frequently Asked Questions
What is the formula to convert Fahrenheit to Celsius?
To convert Fahrenheit (°F) to Celsius (°C), use the formula: (°F − 32) × 5/9 = °C. Subtract 32 from the Fahrenheit temperature, then multiply by 5 and divide by 9.
What is 100 degrees Fahrenheit in Celsius?
100 degrees Fahrenheit equals approximately 37.78 degrees Celsius. This is near the human body temperature of 98.6°F (37°C) and is often used as a reference point.
What is 0 degrees Fahrenheit in Celsius?
0 degrees Fahrenheit equals approximately −17.78 degrees Celsius. This is the freezing point of the Fahrenheit scale, which corresponds to a very cold winter temperature.
What is 212 degrees Fahrenheit in Celsius?
212 degrees Fahrenheit equals exactly 100 degrees Celsius. This is the boiling point of water at standard atmospheric pressure (sea level), making it a key calibration point for both temperature scales.
At what temperature are Fahrenheit and Celsius equal?
Fahrenheit and Celsius are equal at −40 degrees. That means −40°F = −40°C. This is the only temperature where both scales read the same value, occurring at extremely cold conditions.
How do you convert Celsius to Fahrenheit?
To convert Celsius (°C) to Fahrenheit (°F), use the formula: (°C × 9/5) + 32 = °F. Multiply the Celsius temperature by 9, divide by 5, then add 32.
Where is Fahrenheit used compared to Celsius?
Fahrenheit is primarily used in the United States, its territories, and a few other countries for everyday temperature measurements like weather, cooking, and body temperature. Celsius (or Centigrade) is used by most other countries worldwide and is the standard in scientific contexts everywhere, including the US.
Why does the US still use Fahrenheit?
The US continues to use Fahrenheit due to historical tradition and public familiarity. The Fahrenheit scale offers finer granularity (180 degrees between freezing and boiling vs 100 on Celsius), making everyday weather changes more noticeable. Despite several metrication attempts since the 1970s, Fahrenheit remains deeply embedded in American culture.
