25°F is approximately -3.8889°C.
Table of Contents
To convert 25 degrees Fahrenheit to Celsius, you subtract 32 from the Fahrenheit temperature, multiply the result by 5, and then divide by 9. This process changes the scale from Fahrenheit units to Celsius units, which measure temperature differently.

Conversion Formula
The formula to convert Fahrenheit (f) to Celsius (celcius) is:
C = (F – 32) × 5/9
This formula works because Fahrenheit and Celsius scales start at different points, and their increments are different sizes. Fahrenheit sets the freezing point of water at 32 degrees, Celsius at 0. The factor 5/9 adjusts for the different size degrees.
Step-by-step for 25°F:
- Start with 25 (Fahrenheit temperature).
- Subtract 32: 25 – 32 = -7.
- Multiply by 5: -7 × 5 = -35.
- Divide by 9: -35 ÷ 9 ≈ -3.8889.
So, 25°F equals about -3.8889°C.
Conversion Example
- Convert 50°F to Celsius:
- 50 – 32 = 18
- 18 × 5 = 90
- 90 ÷ 9 = 10
- Result: 50°F = 10°C
- Convert 10°F to Celsius:
- 10 – 32 = -22
- -22 × 5 = -110
- -110 ÷ 9 ≈ -12.2222
- Result: 10°F ≈ -12.2222°C
- Convert 0°F to Celsius:
- 0 – 32 = -32
- -32 × 5 = -160
- -160 ÷ 9 ≈ -17.7778
- Result: 0°F ≈ -17.7778°C
- Convert 100°F to Celsius:
- 100 – 32 = 68
- 68 × 5 = 340
- 340 ÷ 9 ≈ 37.7778
- Result: 100°F ≈ 37.7778°C

Conversion Definitions
Fahrenheit (f): Fahrenheit is a temperature scale used mainly in the United States, where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. The scale divides this range into 180 equal parts called degrees Fahrenheit.
Celcius (celcius): Celcius is a temperature scale used worldwide, where water freezes at 0 degrees and boils at 100 degrees under normal atmospheric pressure. Each degree represents one hundredth of the temperature difference between freezing and boiling water.
Conversion FAQs
Why does the formula subtract 32 when converting Fahrenheit to Celsius?
Subtracting 32 adjusts for the difference in zero points between the two scales. Fahrenheit’s zero is set lower than Celsius’s zero, so removing 32 aligns the starting points before scaling the difference by 5/9.
Can the conversion formula be rearranged to convert Celsius to Fahrenheit?
Yes, to convert Celsius to Fahrenheit, multiply by 9/5 then add 32. This reverses the subtraction and division steps used in Fahrenheit to Celsius conversion.
Does the formula work for negative Fahrenheit values?
Yes, negative Fahrenheit temperatures convert using the same formula. The subtraction and multiplication handle negatives correctly, producing the corresponding Celsius value.
Why do some Celsius results have many decimal places?
The conversion involves division by 9, which often produces repeating decimals. You can round the result to the desired precision depending on your need.
Is the Celsius scale more accurate than Fahrenheit?
Accuracy depends on the instrument, not the scale. Celsius divides the freezing and boiling points of water into 100 units, making it simpler for scientific work, but Fahrenheit’s finer increments can be useful for everyday weather reporting.
