28 degrees Fahrenheit is approximately -2.2222 degrees Celsius.
The conversion from Fahrenheit to Celsius involves subtracting 32 from the Fahrenheit value, then multiplying by 5/9. This adjusts the temperature scale so it aligns with Celsius, which has a different zero point and interval size than Fahrenheit.

Conversion Formula
The formula to convert Fahrenheit to Celsius is: C = (F - 32) × 5/9. This formula works because the Fahrenheit and Celsius scales have different starting points and sizes of degrees. Fahrenheit starts at 32 for water’s freezing point, whereas Celsius starts at 0. The factor 5/9 converts the temperature interval from Fahrenheit degrees to Celsius degrees.
For example, converting 28°F:
- Subtract 32 from 28: 28 – 32 = -4
- Multiply by 5/9: -4 × 5/9 = -20/9 ≈ -2.2222
- Result: -2.2222°C
Conversion Example
- Convert 50°F to Celsius:
- 50 – 32 = 18
- 18 × 5/9 = 10
- Result: 10°C
- Convert 0°F to Celsius:
- 0 – 32 = -32
- -32 × 5/9 = -17.7778
- Result: -17.7778°C
- Convert 100°F to Celsius:
- 100 – 32 = 68
- 68 × 5/9 ≈ 37.7778
- Result: 37.7778°C
- Convert 15°F to Celsius:
- 15 – 32 = -17
- -17 × 5/9 ≈ -9.4444
- Result: -9.4444°C
- Convert 77°F to Celsius:
- 77 – 32 = 45
- 45 × 5/9 = 25
- Result: 25°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 range between freezing and boiling into 180 equal intervals called degrees Fahrenheit. It is mainly used in the United States for weather and cooking.
Celsius: Celsius is a metric temperature scale that sets 0 degrees at the freezing point of water and 100 degrees at its boiling point at standard atmospheric pressure. The scale divides this range into 100 equal parts called degrees Celsius, widely used across the world in science and daily life.
Conversion FAQs
Why do we subtract 32 in the Fahrenheit to Celsius formula?
Subtracting 32 adjusts the Fahrenheit temperature to align with the Celsius zero point. Since 32°F represents the freezing point of water, subtracting it shifts the scale so calculations with Celsius degrees become accurate. Without this adjustment, the scales would not correspond correctly.
Can the formula be reversed to convert Celsius to Fahrenheit?
Yes, the opposite conversion from Celsius to Fahrenheit uses the formula: F = (C × 9/5) + 32. The multiplication by 9/5 changes the scale size, and adding 32 repositions the zero point to Fahrenheit’s freezing point of water.
Is it accurate to use approximations like 5/9 in conversion?
The fraction 5/9 is exact for the relative scale difference between Fahrenheit and Celsius degrees. However, rounding during calculations or display might cause slight inaccuracies. Using precise decimal or fraction values keeps conversion results reliable for most purposes.
How does temperature affect the feel of 28°F in Celsius?
28°F equals about -2.22°C, which is below freezing. This temperature causes water to freeze, so it feels cold and icy. Clothing and heating considerations should account for this when switching between the two temperature scales.
Are there any exceptions when converting Fahrenheit to Celsius?
Conversion formulas apply uniformly across all temperatures. However, measurement precision or instrument calibration might affect reported temperatures. The formulas themselves do not have exceptions but care is needed when interpreting readings near extreme temperatures.
