The temperature 0 degrees Celsius equals 32 degrees Fahrenheit.
This conversion comes from the formula that relates Celsius and Fahrenheit scales, where 0°C is the freezing point of water and corresponds to 32°F on the Fahrenheit scale. The formula converts Celsius by multiplying by 9/5 then adding 32.

Conversion Formula
The formula to convert Celsius (C) to Fahrenheit (F) is:
F = (C × 9/5) + 32
This formula works because the Fahrenheit scale sets the freezing point of water at 32°F, while Celsius sets it at 0°C. Multiplying Celsius value by 9/5 adjusts for the difference in scale units, then adding 32 shifts the zero point to Fahrenheit’s freezing mark.
Example: Convert 0°C to Fahrenheit step-by-step:
- Multiply 0 by 9/5: 0 × 9/5 = 0
- Add 32 to the result: 0 + 32 = 32
- So, 0°C equals 32°F
Conversion Example
- Convert 20°C to Fahrenheit:
- Multiply 20 by 9/5: 20 × 9/5 = 36
- Add 32: 36 + 32 = 68
- Result: 20°C = 68°F
- Convert -10°C to Fahrenheit:
- Multiply -10 by 9/5: -10 × 9/5 = -18
- Add 32: -18 + 32 = 14
- Result: -10°C = 14°F
- Convert 37°C to Fahrenheit:
- Multiply 37 by 9/5: 37 × 9/5 = 66.6
- Add 32: 66.6 + 32 = 98.6
- Result: 37°C = 98.6°F
- Convert 100°C to Fahrenheit:
- Multiply 100 by 9/5: 100 × 9/5 = 180
- Add 32: 180 + 32 = 212
- Result: 100°C = 212°F

Conversion Definitions
Celsius (°C): Celsius is a temperature scale used worldwide, where water freezes at 0 degrees and boils at 100 degrees under standard atmospheric pressure. It divides the temperature range between freezing and boiling points into 100 equal parts, making it easy for scientific and everyday uses.
Fahrenheit (°F): Fahrenheit is a temperature scale mainly used in the United States, where water freezes at 32 degrees and boils at 212 degrees. The scale divides this range into 180 parts and was developed in the early 18th century for temperature measurement in weather, cooking, and industry.
Conversion FAQs
Why does the Celsius to Fahrenheit formula add 32?
Adding 32 adjusts the zero point on the Fahrenheit scale to match the freezing point of water. Since 0°C corresponds to 32°F, after scaling the Celsius value by 9/5, adding 32 aligns the scales properly to represent the same physical temperature.
Can the formula be reversed to convert Fahrenheit to Celsius?
Yes, the reverse formula is C = (F – 32) × 5/9. This subtracts 32 from Fahrenheit to reset zero point, then multiplies by 5/9 to adjust scale difference. This way you can convert Fahrenheit temperatures back to Celsius accurately.
Is 0°C always the freezing point of water?
While 0°C is defined as water’s freezing point under standard atmospheric pressure, changes in pressure or impurities in water can alter freezing temperature. But for most practical purposes, 0°C is treated as freezing point.
Why does Fahrenheit use 32 as freezing point?
The Fahrenheit scale was created based on a mixture of ice, water, and salt as zero point, and the freezing point of water was set at 32°F to create a scale with positive values for most temperatures encountered daily. This historical choice remains today.
Can Celsius and Fahrenheit scales be equal at some temperature?
Yes, Celsius and Fahrenheit scales are equal at -40 degrees. This means -40°C equals -40°F, which can be verified by applying the conversion formula and solving for equality.
