0 degrees Celsius converts to 32 degrees Fahrenheit.
The temperature conversion from Celsius to Fahrenheit involves multiplying the Celsius value by 9/5 and then adding 32. This formula adjust the scale difference between the two temperature units, reflecting how water freezes and boils differently on each scale.

Conversion Formula
The formula to convert Celsius (°C) to Fahrenheit (°F) is:
°F = (°C × 9/5) + 32
This formula works because the Celsius and Fahrenheit scales have different zero points and size units. Celsius scale sets 0 at water’s freezing point, while Fahrenheit sets it at 32. Multiplying by 9/5 adjusts the size of one degree Celsius into Fahrenheit units; adding 32 shifts the baseline to Fahrenheit’s zero.
Example: Convert 0°C to °F:
- Multiply 0 by 9/5: 0 × 9/5 = 0
- Add 32 to the result: 0 + 32 = 32°F
Conversion Example
- Convert 25°C to Fahrenheit:
- Multiply 25 by 9/5: 25 × 9/5 = 45
- Add 32: 45 + 32 = 77°F
- Result: 25°C equals 77°F
- Convert -10°C to Fahrenheit:
- Multiply -10 by 9/5: -10 × 9/5 = -18
- Add 32: -18 + 32 = 14°F
- Result: -10°C equals 14°F
- Convert 100°C to Fahrenheit:
- Multiply 100 by 9/5: 100 × 9/5 = 180
- Add 32: 180 + 32 = 212°F
- Result: 100°C equals 212°F
- Convert 15.5°C to Fahrenheit:
- Multiply 15.5 by 9/5: 15.5 × 9/5 = 27.9
- Add 32: 27.9 + 32 = 59.9°F
- Result: 15.5°C equals 59.9°F

Conversion Definitions
Celsius: Celsius is a temperature scale where 0 degrees represents the freezing point of water and 100 degrees the boiling point at standard atmospheric pressure. Each degree Celsius equals one hundredth of the interval between those two points, used worldwide in science and weather reports.
Fahrenheit: Fahrenheit is a temperature scale where 32 degrees marks water’s freezing point and 212 degrees its boiling point, under normal atmospheric conditions. It divides the range into 180 increments, widely used in the United States and some Caribbean nations for weather and cooking.
Conversion FAQs
Why does the formula add 32 after multiplying by 9/5?
The addition of 32 shifts the zero point from Celsius to match Fahrenheit’s zero. Since freezing water is 0°C but 32°F, after scaling the temperature difference by 9/5, 32 is added to align the scales correctly. Without adding 32, freezing point wouldn’t match.
Can I convert Celsius to Fahrenheit by only multiplying?
No, multiplying by 9/5 only adjusts the size of the units but ignores the offset between scales. Because Fahrenheit scale starts at 32 for freezing point, you must add 32 to get the correct temperature in Fahrenheit.
Is the conversion formula valid for negative Celsius temperatures?
Yes, the formula works for all Celsius values, negative or positive. For example, -10°C becomes -10 × 9/5 + 32 = 14°F. The formula accounts for negative inputs correctly.
Why are Celsius and Fahrenheit scales different in the first place?
The two scales were developed independently in history with different reference points and increments. Celsius based on water freezing and boiling, Fahrenheit based on a mix of freezing salt water and human body temperatures, resulting in different zero points and unit sizes.
Can I invert the formula to convert Fahrenheit to Celsius?
Yes, to convert Fahrenheit to Celsius use the inverse formula: (°F – 32) × 5/9. This reverses the addition of 32 and scales the temperature back to Celsius units.
