Fahrenheit to Celsius:
A Fahrenheit to Celsius Converter is an essential tool for converting temperature measurements between the Fahrenheit (°F) scale (used primarily in the United States) and the Celsius (°C) scale (used in most other countries). This conversion is crucial for:
International travel & weather reports
Scientific experiments & medical applications
Cooking & baking recipes
Key Conversion Reference
Freezing point of water: 32°F = 0°C
Boiling point of water: 212°F = 100°C
Absolute zero: -459.67°F = -273.15°C

How to Use a Fahrenheit to Celsius Converter
Enter the temperature in Fahrenheit (°F).
Click "Convert" (or press Enter).
View the result in Celsius (°C).
(Optional) Many converters allow reverse conversion (Celsius to Fahrenheit).
Common Temperature Conversions
| Fahrenheit (°F) | Celsius (°C) | |
|---|---|---|
| -40°F | -40°C | (Same in both scales) |
| 32°F | 0°C | (Water freezes) |
| 68°F | 20°C | (Room temperature) |
| 98.6°F | 37°C | (Human body temperature) |
| 212°F | 100°C | (Water boils) |
Why Convert Fahrenheit to Celsius?
Travel & Weather – Many countries use Celsius for weather forecasts.
Science & Medicine – Most global research uses Celsius or Kelvin.
Cooking – Recipes from different countries may use different scales.
Manual Calculation Example
Problem: Convert 77°F to Celsius.
Solution:
So, 77°F = 25°C (a warm day).
Quick Reference Tips
For rough estimates: Subtract 30 from °F, then halve it (e.g., 100°F ≈ (100-30)/2 = 35°C).
Key temperatures to remember:
0°C = 32°F (freezing)
20°C = 68°F (room temp)
37°C = 98.6°F (body temp)
