10 Fahrenheit is equal to approximately -12.2222 Celsius.
To convert 10 degrees Fahrenheit to Celsius, we apply the formula that adjusts for the difference in zero points and scales of the two temperature units. Since Fahrenheit and Celsius differ not only in their zero points but also in the size of their degrees, the formula subtracts 32 from the Fahrenheit value and multiplies by 5/9 to find the equivalent Celsius temperature.

Conversion Formula
The formula to convert Fahrenheit (°F) to Celsius (°C) is:
Celsius = (Fahrenheit – 32) × 5/9
This works because the Fahrenheit scale sets its zero point at a different temperature than Celsius, and the size of one degree Fahrenheit is smaller than one degree Celsius. To adjust, first subtract 32 from the Fahrenheit temperature to shift the zero point, then multiply by 5/9 to adjust the scale size difference.
Example: Convert 10°F to Celsius step-by-step:
- Subtract 32: 10 – 32 = -22
- Multiply by 5/9: -22 × 5/9 ≈ -12.2222
- Result: 10°F equals about -12.2222°C
Conversion Example
- Convert 50°F to Celsius:
- Subtract 32: 50 – 32 = 18
- Multiply by 5/9: 18 × 5/9 = 10
- Result: 50°F equals 10°C
- Convert -40°F to Celsius:
- Subtract 32: -40 – 32 = -72
- Multiply by 5/9: -72 × 5/9 = -40
- Result: -40°F equals -40°C (the point where both scales meet)
- Convert 77°F to Celsius:
- Subtract 32: 77 – 32 = 45
- Multiply by 5/9: 45 × 5/9 = 25
- Result: 77°F equals 25°C
- Convert 0°F to Celsius:
- Subtract 32: 0 – 32 = -32
- Multiply by 5/9: -32 × 5/9 ≈ -17.7778
- Result: 0°F equals about -17.7778°C

Conversion Definitions
Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It divides the temperature range between freezing and boiling of water into 180 equal parts called degrees. This scale is primarily used in the United States and some Caribbean countries.
Celsius: Celsius is a temperature scale with 0 degrees set as the freezing point of water and 100 degrees as the boiling point at sea level pressure. Each degree represents one hundredth of this temperature range. Celsius is used worldwide in scientific and everyday temperature measurements, especially outside the US.
Conversion FAQs
Why does the formula subtract 32 from Fahrenheit when converting to Celsius?
The 32 subtraction adjusts for the offset between the two scales’ zero points. Fahrenheit zero is set at a lower temperature than Celsius zero. Removing 32 aligns the Fahrenheit temperature to the Celsius zero point before scaling the degree size difference. Without this, the conversion would be inaccurate.
Can the conversion formula be reversed to convert Celsius to Fahrenheit?
Yes, the reverse formula is Fahrenheit = (Celsius × 9/5) + 32. This multiplies the Celsius temperature by 9/5 to scale up to Fahrenheit degrees, then adds 32 to shift the zero point back to Fahrenheit scale. This reversal works because the two scales are linearly related.
Does converting 10°F to Celsius always result in a negative number?
Not always, but in this case yes. Since 10°F is less than 32°F (freezing point in Fahrenheit), its Celsius equivalent will be below zero, resulting in a negative Celsius temperature. Temperatures above 32°F will convert to positive Celsius values.
Is the conversion formula exact or approximate?
The formula is exact within the precision limits of decimal representation. Fahrenheit and Celsius scales relate by a precise linear function, so the formula gives an exact mathematical conversion. However, temperature measurements themselves can have minor errors or rounding differences.
Why do some conversion results have many decimal places?
Because the ratio 5/9 is an irrational fraction in decimal form, converting Fahrenheit to Celsius may result in decimal numbers with many digits. Rounding to a certain number of decimal places is common to make the values practical while keeping enough precision for typical uses.
