25 degrees Fahrenheit is approximately -3.8889 degrees Celsius.
To convert 25°F to Celsius, subtract 32 from the Fahrenheit value, then multiply the result by 5/9. This shifts and scales the temperature from the Fahrenheit scale to the Celsius scale, reflecting the difference in zero points and unit sizes.

Conversion Formula
The formula to convert Fahrenheit (f) to Celsius (°C) is:
Celsius = (Fahrenheit – 32) × 5/9
This formula subtracts 32 because 32°F is the freezing point of water, which equals 0°C. Multiplying by 5/9 adjusts for the different size of the degrees on each scale. Fahrenheit degrees are smaller, so we scale the difference to match Celsius units.
Example:
- Start with 25°F
- Subtract 32: 25 – 32 = -7
- Multiply by 5/9: -7 × 5/9 = -3.8889°C
Conversion Example
- Convert 68°F to Celsius:
- Subtract 32: 68 – 32 = 36
- Multiply by 5/9: 36 × 5/9 = 20°C
- Convert 10°F to Celsius:
- Subtract 32: 10 – 32 = -22
- Multiply by 5/9: -22 × 5/9 = -12.2222°C
- Convert 50°F to Celsius:
- Subtract 32: 50 – 32 = 18
- Multiply by 5/9: 18 × 5/9 = 10°C
- Convert 0°F to Celsius:
- Subtract 32: 0 – 32 = -32
- Multiply by 5/9: -32 × 5/9 = -17.7778°C

Conversion Definitions
Fahrenheit (f): Fahrenheit is a temperature scale in which water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It’s commonly used in the United States and a few other countries to measure temperature in weather forecasts, cooking, and industry.
Celsius: Celsius is a temperature scale where 0 degrees is the freezing point of water and 100 degrees is boiling point at normal atmospheric pressure. It is widely used in science and most countries worldwide for daily temperature measurements and scientific work.
Conversion FAQs
Why do we subtract 32 when converting Fahrenheit to Celsius?
The Fahrenheit scale sets 32 degrees as the freezing point of water, while Celsius uses 0 degrees for freezing. Subtracting 32 shifts the Fahrenheit value down to align the zero points before scaling the temperature difference by 5/9.
Can this conversion formula be used for negative Fahrenheit values?
Yes, the formula works for negative Fahrenheit temperatures as well. Negative Fahrenheit values represent temperatures below freezing, and the formula converts them correctly to negative Celsius values, reflecting colder temperatures on the Celsius scale.
Why multiply by 5/9 in the conversion?
The size of one degree on the Fahrenheit scale is smaller than on Celsius. There are 180 Fahrenheit degrees between freezing and boiling water, but only 100 Celsius degrees. Multiplying by 5/9 scales the temperature difference to match Celsius units.
Is the conversion exact or approximate?
The formula gives an exact mathematical conversion between the two scales. However, rounding decimals may cause small differences when displayed. For practical purposes, using four decimal places is precise enough.
Are there simpler ways to estimate Fahrenheit to Celsius?
Some approximate methods exist, like subtracting 30 and halving the result, but they are less accurate. The formula (F – 32) × 5/9 provides precise conversions needed for scientific or detailed temperature work.
