1 Celsius equals 33.8 Fahrenheit.
To convert 1 degree Celsius to Fahrenheit, multiply by 9/5 and then add 32. This converts the scale from Celsius, based on freezing and boiling points of water, to Fahrenheit, which uses a different zero and scaling system.

Conversion Formula
The formula to convert Celsius to Fahrenheit is: F = (C × 9/5) + 32. This means you multiply the Celsius temperature by 9 divided by 5, then add 32 to the result. 9/5 is the ratio of Fahrenheit degree size to Celsius, and 32 accounts for the difference in zero points on both scales.
Because Celsius sets freezing water point at 0 and boiling at 100, and Fahrenheit sets freezing at 32 and boiling at 212, the formula adjusts the scale and zero offset.
Example for 1°C:
- Multiply 1 by 9: 1 × 9 = 9
- Divide 9 by 5: 9 ÷ 5 = 1.8
- Add 32: 1.8 + 32 = 33.8°F
Conversion Example
- Convert 10°C to Fahrenheit:
- Multiply 10 × 9 = 90
- Divide 90 ÷ 5 = 18
- Add 32: 18 + 32 = 50°F
- Convert -5°C to Fahrenheit:
- Multiply -5 × 9 = -45
- Divide -45 ÷ 5 = -9
- Add 32: -9 + 32 = 23°F
- Convert 20°C to Fahrenheit:
- Multiply 20 × 9 = 180
- Divide 180 ÷ 5 = 36
- Add 32: 36 + 32 = 68°F
- Convert 0°C to Fahrenheit:
- Multiply 0 × 9 = 0
- Divide 0 ÷ 5 = 0
- Add 32: 0 + 32 = 32°F

Conversion Definitions
Celsius: Celsius is a temperature scale where 0 degrees marks the freezing point of water and 100 degrees the boiling point at sea level. It’s widely used internationally for weather, science, and everyday temperature readings, based on the metric system.
Fahrenheit: Fahrenheit is a temperature scale used mainly in the United States, where water freezes at 32 degrees and boils at 212 degrees. It divides the temperature range into 180 equal parts between freezing and boiling points of water.
Conversion FAQs
Why does the formula add 32 after multiplying by 9/5?
The addition of 32 adjusts for the offset between the zero points of Celsius and Fahrenheit scales. Celsius zero is the freezing point of water, but Fahrenheit sets freezing at 32 degrees, so the +32 shifts the scaled value accordingly.
Can negative Celsius temperatures be converted the same way?
Yes, the formula applies the same, even for negative Celsius values. For example, -10°C converts to 14°F by multiplying -10 by 9/5 (-18) and then adding 32, resulting 14°F.
Is the formula reversible for Fahrenheit to Celsius?
To convert Fahrenheit back to Celsius, the formula reverses: subtract 32, then multiply by 5/9. This reverses the offset and scaling applied when converting Celsius to Fahrenheit.
Why is 1 Celsius a decimal number in Fahrenheit?
Because the temperature scales use different increments, converting 1 Celsius results in 33.8 Fahrenheit, a decimal value. The scaling factor 9/5 and offset 32 produce non-integer results for most Celsius values.
Does this formula work for all temperature ranges?
The formula works for all temperatures, including extreme or fractional values, as it mathematically relates the two scales linearly. However, physical phenomena at extreme conditions may require other considerations.
