Conversion Formula
The conversion between Celsius and Fahrenheit is based on the following formulas:
Where:
- °F is the temperature in degrees Fahrenheit
- °C is the temperature in degrees Celsius
These formulas are derived from the linear relationship between the two temperature scales.
Common Temperature Conversions
Here are some common temperature conversions between Celsius and Fahrenheit:
| Celsius (°C) | Fahrenheit (°F) | Description |
|---|---|---|
| 0 | 32 | Freezing point of water |
| 100 | 212 | Boiling point of water |
| -40 | -40 | Identical in both scales |
| 37 | 98.6 | Average human body temperature |
| -273.15 | -459.67 | Absolute zero |

Frequently Asked Questions
What is the difference between Celsius and Fahrenheit?
Celsius and Fahrenheit are two different temperature scales. Celsius is used in most countries and is based on the freezing point of water (0°C) and boiling point (100°C). Fahrenheit is used primarily in the United States and is based on a different scale where water freezes at 32°F and boils at 212°F.
How do I convert Celsius to Fahrenheit?
To convert Celsius to Fahrenheit, use the formula: °F = (°C × 9/5) + 32. For example, 25°C is equal to 77°F.
What is the freezing point of water in Fahrenheit?
The freezing point of water is 32°F (0°C). This is a key reference point in both temperature scales.
Why do different countries use different temperature scales?
Different countries adopted different temperature scales based on historical and practical reasons. Celsius is part of the metric system, while Fahrenheit was developed independently. Most countries now use Celsius, but Fahrenheit remains in common use in the United States and a few other places.
