Fahrenheit to Centigrade Converter
Use this free calculator to instantly convert any temperature from degrees Fahrenheit (°F) to centigrade/celsius (°C).
Formula used: (°F − 32) × 5/9 = °C
What This Fahrenheit to Centigrade Calculator Does
This calculator converts temperatures from Fahrenheit to centigrade (also called Celsius) instantly. It is useful for weather readings, cooking temperatures, science homework, travel planning, and any situation where you need to move between temperature scales quickly and accurately.
In the United States, Fahrenheit is commonly used for daily weather and many household settings. In most other countries and in scientific contexts, centigrade/Celsius is the standard. A simple conversion tool helps prevent mistakes and saves time.
Fahrenheit to Centigrade Formula
The exact equation
To convert Fahrenheit to centigrade, subtract 32 from the Fahrenheit value and then multiply by 5/9:
°C = (°F − 32) × 5/9
Example conversion
- Start with 68°F
- Subtract 32: 68 − 32 = 36
- Multiply by 5/9: 36 × 5/9 = 20
- Result: 68°F = 20°C
How to Use the Calculator
- Enter a Fahrenheit value in the input field.
- Select how many decimal places you want in the final answer.
- Click Convert to Centigrade.
- Read your converted value in both the result box and output field.
Tip: You can enter negative values as well, such as -40°F, which equals -40°C.
Common Fahrenheit to Centigrade Reference Points
| Fahrenheit (°F) | Centigrade (°C) | Meaning |
|---|---|---|
| -40°F | -40°C | Point where both scales match |
| 32°F | 0°C | Water freezing point |
| 68°F | 20°C | Mild room temperature |
| 98.6°F | 37°C | Average human body temperature |
| 212°F | 100°C | Water boiling point at sea level |
Why Accurate Conversion Matters
- Health: Correct body temperature interpretation can be important.
- Cooking: Oven and recipe settings often vary by region.
- Science and engineering: Precision is essential for reliable results.
- Travel: Understand weather reports and climate conditions abroad.
