0 degrees Celsius equals 32 degrees Fahrenheit.
When converting 0 Celsius to Fahrenheit, we use the formula to change the temperature scale from Celsius, which is based on the freezing point of water at 0, to Fahrenheit, where water freezes at 32 degrees. The calculation shows how these scales relate by shifting and scaling the value.

Conversion Formula
The formula to convert Celsius to Fahrenheit is: Fahrenheit = (Celsius × 9/5) + 32. This formula works by scaling the Celsius temperature by 9/5, because the Fahrenheit degree is smaller, and then adding 32 to adjust for the offset where water freezes at 32°F instead of 0°C.
Breaking down the formula:
- Multiply the Celsius temperature by 9/5 to change the size of the temperature unit.
- Add 32 to shift the scale to Fahrenheit’s zero point.
Example: To convert 0°C:
- 0 × 9/5 = 0
- 0 + 32 = 32°F
Conversion Example
- Convert 10°C to Fahrenheit:
- Multiply 10 by 9/5: 10 × 1.8 = 18
- Add 32: 18 + 32 = 50°F
- Convert -5°C to Fahrenheit:
- -5 × 1.8 = -9
- -9 + 32 = 23°F
- Convert 20°C to Fahrenheit:
- 20 × 1.8 = 36
- 36 + 32 = 68°F
- Convert 15.5°C to Fahrenheit:
- 15.5 × 1.8 = 27.9
- 27.9 + 32 = 59.9°F

Conversion Definitions
Celsius: Celsius is a temperature scale where water freezes at 0 degrees and boils at 100 degrees under standard atmospheric pressure. It is widely used around the world for daily temperature measurement and scientific purposes, based on the metric system’s decimal structure.
Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees at sea level. It was created in the 18th century and remains primarily used in the United States and a few other countries for weather and cooking temperatures.
Conversion FAQs
Why does the Celsius to Fahrenheit formula add 32?
The addition of 32 adjusts for the difference in zero points between the two scales. Celsius sets freezing water at 0°, but Fahrenheit sets freezing at 32°. By adding 32, we shift the scaled Celsius temperature so it matches the Fahrenheit scale’s baseline.
Can the conversion formula be reversed?
Yes, to convert Fahrenheit back to Celsius, you subtract 32 first and then multiply by 5/9. The formula is Celsius = (Fahrenheit – 32) × 5/9. This reverses the scaling and shifting done in the forward conversion.
Is 0 Celsius always equal to 32 Fahrenheit for all conditions?
The freezing point of water is defined as 0°C and 32°F at standard atmospheric pressure. Changes in pressure or impurities in water can slightly shift freezing points, but in practical everyday use, 0°C equals exactly 32°F.
Why multiply by 9/5 in the formula?
The 9/5 factor converts the size of a degree Celsius into the size of a degree Fahrenheit. Since there are 180 Fahrenheit degrees between freezing and boiling versus 100 Celsius degrees, each Celsius degree equals 1.8 Fahrenheit degrees, thus the ratio 9/5.
Does this conversion work for negative Celsius values?
Yes, the formula works for any real number, including negatives. For example, -10°C converts to 14°F by multiplying -10 by 9/5 and adding 32, resulting in 14°F. Negative values behave the same way mathematically.
