28 degrees Fahrenheit is approximately -2.2222 degrees Celsius.
To convert 28°F to degrees Celsius, you subtract 32 from the Fahrenheit value, multiply the result by 5, and then divide by 9. This transforms the Fahrenheit scale into the Celsius scale, which measures temperature differently.

Conversion Formula
The formula to convert Fahrenheit (F) to degrees Celsius (C) is:
C = (F – 32) × 5/9
This formula works by subtracting 32 from the Fahrenheit temperature to adjust for the offset between the two scales. Then, multiplying by 5 and dividing by 9 changes the scale size because 180 Fahrenheit degrees equal 100 Celsius degrees. This ratio rescales the value to Celsius properly.
Example: Convert 28°F to Celsius step-by-step:
- Subtract 32: 28 – 32 = -4
- Multiply by 5: -4 × 5 = -20
- Divide by 9: -20 ÷ 9 ≈ -2.2222
- Result: -2.2222°C
Conversion Example
- Convert 50°F to Celsius:
- Subtract 32: 50 – 32 = 18
- Multiply by 5: 18 × 5 = 90
- Divide by 9: 90 ÷ 9 = 10
- So, 50°F equals 10°C
- Convert 10°F to Celsius:
- Subtract 32: 10 – 32 = -22
- Multiply by 5: -22 × 5 = -110
- Divide by 9: -110 ÷ 9 ≈ -12.2222
- Result: -12.2222°C
- Convert 100°F to Celsius:
- Subtract 32: 100 – 32 = 68
- Multiply by 5: 68 × 5 = 340
- Divide by 9: 340 ÷ 9 ≈ 37.7778
- Result: 37.7778°C
- Convert 0°F to Celsius:
- Subtract 32: 0 – 32 = -32
- Multiply by 5: -32 × 5 = -160
- Divide by 9: -160 ÷ 9 ≈ -17.7778
- Result: -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 is primarily used in the United States and some Caribbean countries, and measures temperature based on these reference points.
Degrees: Degrees is a unit of measurement for temperature that quantifies how hot or cold a substance is. When used with scales like Celsius or Fahrenheit, it indicates the spacing between points on the scale representing temperature values.
Conversion FAQs
Why does the conversion subtract 32 from Fahrenheit temperature?
Subtracting 32 adjusts for the different zero points between Fahrenheit and Celsius scales. While Celsius zero is based on water freezing, Fahrenheit zero was set differently, so removing 32 aligns the starting point for the scale conversion.
Can the conversion formula be reversed to get Fahrenheit from Celsius?
Yes, the inverse formula is F = (C × 9/5) + 32. This reverses the scaling and offset steps, converting Celsius back to Fahrenheit, adding the 32 offset after scaling by 9/5.
Why does 28°F convert to a negative Celsius value?
Because 28°F is below the freezing point of water (32°F), its Celsius equivalent is below zero. So the result is a negative number, indicating temperatures colder than freezing in Celsius terms.
Is the formula accurate for all temperatures?
The formula applies to all temperatures, including extreme values. It is based on linear scaling between the two temperature systems, so it works no matter how hot or cold the measurement is.
Does rounding affect the conversion?
Yes, rounding the result can affect precision. Using several decimal places gives a more exact conversion, but for everyday use, rounding to one or two decimals is usually fine.
