Fahrenheit to Celsius Formula:
| From: | To: |
The Fahrenheit to Celsius conversion is a mathematical formula used to convert temperature values from the Fahrenheit scale to the Celsius scale. This is particularly important for scientific applications, international communication, and understanding temperature measurements in different regions of the world.
The calculator uses the conversion formula:
Where:
Explanation: The formula subtracts 32 from the Fahrenheit temperature and then multiplies the result by 5/9 to get the equivalent Celsius temperature.
Details: Accurate temperature conversion is essential for scientific research, international travel, cooking, medical applications, and understanding weather reports from different countries that use different temperature scales.
Tips: Enter the temperature in Fahrenheit that you want to convert to Celsius. The calculator will automatically compute and display the equivalent Celsius temperature.
Q1: What is the freezing point of water in both scales?
A: Water freezes at 32°F (0°C) and boils at 212°F (100°C) at standard atmospheric pressure.
Q2: Which countries use Fahrenheit vs Celsius?
A: The United States and its territories primarily use Fahrenheit, while most other countries use Celsius as their standard temperature scale.
Q3: Is there a simple way to approximate the conversion?
A: A quick approximation is to subtract 30 from the Fahrenheit temperature and then divide by 2, though this is less accurate than the precise formula.
Q4: What is absolute zero in both scales?
A: Absolute zero is -459.67°F (-273.15°C), the theoretical lowest possible temperature.
Q5: Why are there different temperature scales?
A: Different scales were developed by different scientists (Fahrenheit by Daniel Fahrenheit, Celsius by Anders Celsius) at different times with different reference points.
