How to learn Celsius from Fahrenheit?

I'm taking a science class with international students, and sometimes temperatures are in Celsius instead of Fahrenheit. Do you have any tips or tricks to learn and understand Celsius, so I don't struggle with this during tests and courses? Thanks!

Sure! To convert between Fahrenheit and Celsius, you can use the following formulas:

1. To convert Celsius to Fahrenheit: (°C × 9/5) + 32 = °F

2. To convert Fahrenheit to Celsius: (°F - 32) x 5/9 = °C

Here's a trick to help you with some mental approximations without using the exact formula:

When converting from Fahrenheit to Celsius:

- Subtract 30 from the Fahrenheit temperature, then divide by 2. This gives you a close estimate of the Celsius temperature.

For example, if the temperature is 70°F:

(70 - 30) / 2 ≈ 20°C (actual value: 21°C)

When converting from Celsius to Fahrenheit:

- Double the Celsius temperature, then add 30. This gives you a close estimate of the Fahrenheit temperature.

For example, if the temperature is 20°C:

(20 x 2) + 30 ≈ 70°F (actual value: 68°F)

Keep in mind that these are just approximations, but they should be sufficient to give you a general idea about the temperature when you don't have a calculator handy. For precise conversions during tests and courses, it's best to use the formulas mentioned above. Practicing with different temperatures will also help improve your intuition and understanding of the Celsius scale. Good luck with your science class!
