Understanding the Basics
The Fahrenheit scale is a temperature scale that is commonly used in the United States, while the Celsius scale is used in most other parts of the world. The Fahrenheit scale is based on the freezing point of water (32°F) and the boiling point of water (212°F), while the Celsius scale is based on the freezing point of water (0°C) and the boiling point of water (100°C).
When converting from Fahrenheit to Celsius, you need to know that the difference between the two scales is about 1.8°C for every 1°F. This means that if you want to convert a temperature from Fahrenheit to Celsius, you need to subtract 32 from the Fahrenheit temperature and then multiply the result by 5 and divide it by 9.
For example, if you want to convert 90°F to Celsius, you can follow these steps: subtract 32 from 90 to get 58, then multiply 58 by 5 to get 290, and finally divide 290 by 9 to get 32.22°C.
Step-by-Step Conversion
To convert 90°F to Celsius, follow these steps:
- Subtract 32 from the Fahrenheit temperature: 90 - 32 = 58
- Multiply the result by 5: 58 x 5 = 290
- Divide the result by 9: 290 / 9 = 32.22
Therefore, 90°F is equal to 32.22°C.
Using a Conversion Table
Here's a table that shows the conversion from Fahrenheit to Celsius for temperatures up to 90°F:
| Fahrenheit | Celsius |
|---|---|
| 80 | 27.22 |
| 82 | 28.89 |
| 84 | 29.44 |
| 86 | 30.00 |
| 88 | 31.11 |
| 90 | 32.22 |
As you can see, the table shows the conversion from Fahrenheit to Celsius for temperatures up to 90°F.
