How to convert between Fahrenheit and Celsius?
Converting between temperature scales is fundamental in science, cooking, and daily life. The formulas use specific operations due to the different reference points of each scale.
Conversion formulas:
From Fahrenheit to Celsius:
°C = (°F - 32) × 5/9
From Celsius to Fahrenheit:
°F = (°C × 9/5) + 32
Practical examples
Water freezing point:
32°F = 0°C
Calculation: (32 - 32) × 5/9 = 0°C
Typical room temperature:
20°C = 68°F
Calculation: (20 × 9/5) + 32 = 68°F
Water boiling point:
100°C = 212°F
Calculation: (100 × 9/5) + 32 = 212°F
Important reference points
| Event | Celsius | Fahrenheit |
|---|---|---|
| Water freezing | 0°C | 32°F |
| Room temperature | 20°C | 68°F |
| Body temperature | 37°C | 98.6°F |
| Water boiling | 100°C | 212°F |
Common uses
- Cooking: Recipes and cooking temperatures
- Weather: Weather forecast and ambient temperature
- Medicine: Body temperature measurement
- Industry: Industrial processes and quality control
Historical fact
The Fahrenheit scale was proposed by Daniel Gabriel Fahrenheit in 1724, while the Celsius scale was created by Anders Celsius in 1742. The Celsius scale is used in most countries, while Fahrenheit is primarily used in the United States and some specific territories.
