Conversion Formula
The formula to convert from fahrenheit (°F) to celsius (°C) is:
Celsius = (Fahrenheit – 32) × 5/9
This formula works by first adjusting the Fahrenheit scale, removing the freezing point offset of 32 degrees, then scaling the number down by multiplying by 5/9 because the size of one degree Celsius is larger than one degree Fahrenheit.
Example for 25°F:
- Subtract 32: 25 – 32 = -7
- Multiply by 5/9: -7 × 5/9 = -35/9 ≈ -3.8889
- Result: -3.8889°C
Conversion Example
- Convert 50°F to Celsius:
- Subtract 32: 50 – 32 = 18
- Multiply by 5/9: 18 × 5/9 = 10
- Result: 10°C
- Convert 77°F to Celsius:
- Subtract 32: 77 – 32 = 45
- Multiply by 5/9: 45 × 5/9 = 25
- Result: 25°C
- Convert 10°F to Celsius:
- Subtract 32: 10 – 32 = -22
- Multiply by 5/9: -22 × 5/9 ≈ -12.2222
- Result: -12.2222°C
- Convert 0°F to Celsius:
- Subtract 32: 0 – 32 = -32
- Multiply by 5/9: -32 × 5/9 ≈ -17.7778
- Result: -17.7778°C

Conversion Definitions
Fahrenheit: Fahrenheit is a temperature scale using degrees where water freezes at 32 and boils at 212 under standard atmospheric pressure. It is mainly used in the United States and some Caribbean countries, measuring temperature in increments that are smaller than Celsius.
Celsius: Celsius, also known as centigrade, measures temperature with 0 as freezing point of water and 100 as boiling point at sea level. It is widely used worldwide in science and everyday life, offering a decimal-based scale for temperature.
Conversion FAQs
Why do we subtract 32 in the Fahrenheit to Celsius conversion?
Subtracting 32 adjusts the Fahrenheit temperature by removing the offset between the two scales’ zero points. Since 32°F represents the freezing point of water, which is zero in Celsius, this shift aligns the two scales before scaling the difference.
Can I convert Fahrenheit to Celsius without a calculator?
Yes, by using the formula (F – 32) × 5/9, you can do the math manually. For rough estimates, subtract 30 and divide by 2, but this shortcuts less accurate. The exact method requires subtraction and multiplication or division.
Why is the multiplication factor 5/9 in the formula?
The factor 5/9 comes from the ratio of the degree sizes on the two scales. Each Fahrenheit degree is 5/9 the size of a Celsius degree because Fahrenheit divides the interval between freezing and boiling of water into 180 parts, Celsius into 100 parts.
Is 25°F considered cold in Celsius terms?
Yes, 25°F converts to about -3.89°C, which is below freezing point. This temperature is cold enough to freeze water and cause frost, so it indicates a chilly environment in Celsius terms.
Does this conversion formula work for negative Fahrenheit values?
Yes, the formula applies for all Fahrenheit values, positive or negative. Negative Fahrenheit temperatures convert correctly by subtracting 32 and multiplying by 5/9, yielding negative Celsius values representing cold temperatures.
