How to convert Celsius to Fahrenheit?
Converting Celsius to Fahrenheit is slightly more complex than length or weight conversions because the two scales start at different points.
- 0°C (Freezing point of water) = 32°F
- 100°C (Boiling point of water) = 212°F
To convert Celsius to Fahrenheit, you need to multiply by 1.8 (or 9/5) and then add 32.
Formula: Fahrenheit = (Celsius × 1.8) + 32
Step-by-Step Calculation
- Take the temperature in Celsius (e.g., 20°C).
- Multiply it by 9.
- Divide the result by 5 (or just multiply by 1.8).
- Add 32 to that number.
- The result is the temperature in Fahrenheit. (Example: 20 × 1.8 = 36; 36 + 32 = 68°F).

Frequently Asked Questions
What is normal body temperature in Fahrenheit?
Normal human body temperature is 37°C, which converts to 98.6°F.
How do I mentally convert C to F?
A quick estimation trick: Double the Celsius figure and add 30. (e.g., 20°C × 2 = 40; 40 + 30 = 70°F). It's close to the actual 68°F.
At what temperature are Celsius and Fahrenheit the same?
They intersect at -40 degrees. So, -40°C is exactly the same as -40°F.
What is 20 degrees Celsius in Fahrenheit?
20°C is equal to 68°F, which is generally considered a comfortable room temperature.
