25 degrees Fahrenheit is equal to -3.8889 degrees Celsius.
To convert 25°F to Celsius, subtract 32 from the Fahrenheit value, multiply the result by 5, then divide by 9. This adjusts the scale difference and zero points between the two temperature systems.

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 have different zeros and increments per degree. Fahrenheit sets water freezing point at 32, Celsius at 0. So, subtracting 32 shifts the zero points aligned, then multiplying by 5/9 converts the degree size difference.
Step-by-step for 25°F:
- Subtract 32 from 25: 25 – 32 = -7
- Multiply -7 by 5: -7 × 5 = -35
- Divide -35 by 9: -35 ÷ 9 ≈ -3.8889
- Result is approximately -3.8889°C
Conversion Example
Convert 68°F to Celsius:
- Subtract 32: 68 – 32 = 36
- Multiply by 5: 36 × 5 = 180
- Divide by 9: 180 ÷ 9 = 20
- So, 68°F equals 20°C
Convert 0°F to Celsius:
- Subtract 32: 0 – 32 = -32
- Multiply by 5: -32 × 5 = -160
- Divide by 9: -160 ÷ 9 ≈ -17.7778
- 0°F equals about -17.7778°C
Convert 100°F to Celsius:
- Subtract 32: 100 – 32 = 68
- Multiply by 5: 68 × 5 = 340
- Divide by 9: 340 ÷ 9 ≈ 37.7778
- 100°F equals about 37.7778°C

Conversion Definitions
f: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It divides the interval between these points into 180 equal parts called degrees Fahrenheit, commonly used in the United States and some Caribbean countries.
celcius: Celsius is a temperature scale used worldwide, where 0 degrees represents water freezing point and 100 degrees water boiling point at sea level pressure. Each degree Celsius represents an equal temperature increment, making it a metric scale for temperature measurement.
Conversion FAQs
Why is the Celsius value negative when converting from 25°F?
Since 25°F is below the freezing point of water in Fahrenheit (32°F), converting to Celsius results in a value below 0°C. The formula shifts the zero by subtracting 32, so temperatures under 32°F become negative Celsius values.
Can the conversion formula be used for decimal Fahrenheit values?
Yes, the formula works on any numeric Fahrenheit input, including decimals. The calculation follows the same steps: subtract 32, multiply by 5, and divide by 9. This allows precise conversion for fractional temperatures.
Does the conversion formula change at different altitudes or pressures?
The formula only converts numeric values between scales and doesn’t consider physical changes due to pressure or altitude. The freezing and boiling points of water vary under different conditions, but the formula assumes standard atmospheric pressure.
How accurate is the formula for weather reporting?
The formula provides very accurate conversions suitable for weather data, scientific applications, and daily use. Minor rounding errors can appear when limiting decimal places, but the underlying math is exact for converting between Fahrenheit and Celsius.
Is there a direct formula to convert Celsius to Fahrenheit?
Yes, to convert Celsius to Fahrenheit, multiply the Celsius value by 9/5 and add 32. This reverses the conversion process, aligning the Celsius scale back to Fahrenheit’s zero and scaling increments properly.
