How to Convert Celsius to Fahrenheit
To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 (or 1.8) and then add 32. This conversion is based on the relationship between the two temperature scales.
Fahrenheit = (Celsius × 9/5) + 32
Example:
To convert 20 degrees Celsius to Fahrenheit:
- Fahrenheit = (20°C × 9/5) + 32
- Fahrenheit = 36 + 32
- Fahrenheit = 68°F
How to Convert Fahrenheit to Celsius
To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and then multiply by 5/9 (or divide by 1.8).
Celsius = (Fahrenheit - 32) × 5/9
Example:
To convert 68 degrees Fahrenheit to Celsius:
- Celsius = (68°F - 32) × 5/9
- Celsius = 36 × 5/9
- Celsius = 20°C

Frequently Asked Questions
To convert Celsius to Fahrenheit, use the formula: Fahrenheit = (Celsius × 9/5) + 32. For example, to convert 20°C to Fahrenheit: (20 × 9/5) + 32 = 68°F.
To convert Fahrenheit to Celsius, use the formula: Celsius = (Fahrenheit - 32) × 5/9. For example, to convert 68°F to Celsius: (68 - 32) × 5/9 = 20°C.
Celsius and Fahrenheit are equal at -40 degrees. This is the only point where the two temperature scales have the same numerical value: -40°C = -40°F.
0°C is equal to 32°F. This is the freezing point of water in both temperature scales.
100°C is equal to 212°F. This is the boiling point of water at standard atmospheric pressure.
Room temperature is typically defined as around 20-22°C, which is approximately 68-72°F.
Most countries in the world use Celsius as their primary temperature scale. The United States is the main country that still primarily uses Fahrenheit for everyday temperature measurements. A few other countries such as the Bahamas, Belize, the Cayman Islands, and Palau also use Fahrenheit.
