27 degrees Fahrenheit is approximately -2.7778 degrees Celsius.
To convert 27 degrees Fahrenheit to Celsius, you subtract 32 from the Fahrenheit value, then multiply by 5/9. This formula adjusts for the difference in zero points and scale between the two temperature units.

Conversion Formula
The formula to convert degrees Fahrenheit to Celsius is:
Celsius = (Fahrenheit – 32) × 5/9
This works because Fahrenheit and Celsius scales start at different points, with water freezing at 32°F and 0°C. The 5/9 factor adjusts for the fact that each degree Fahrenheit is 5/9 the size of a Celsius degree.
Example using 27°F:
Step 1: Subtract 32 from 27 → 27 – 32 = -5
Step 2: Multiply by 5/9 → -5 × 5/9 = -25/9 ≈ -2.7778°C
Conversion Example
- Convert 50°F to Celsius:
- Subtract 32: 50 – 32 = 18
- Multiply by 5/9: 18 × 5/9 = 10°C
- Convert 10°F to Celsius:
- Subtract 32: 10 – 32 = -22
- Multiply by 5/9: -22 × 5/9 = -12.2222°C
- Convert 100°F to Celsius:
- Subtract 32: 100 – 32 = 68
- Multiply by 5/9: 68 × 5/9 = 37.7778°C
- Convert 0°F to Celsius:
- Subtract 32: 0 – 32 = -32
- Multiply by 5/9: -32 × 5/9 = -17.7778°C

Conversion Definitions
Degrees: Units used to measure temperature or angles, representing increments of a full scale. In temperature, degrees quantify hotness or coldness, with different scales like Fahrenheit and Celsius having distinct zero points and step sizes for the degree units.
Celsius: A temperature scale based on water freezing at 0°C and boiling at 100°C, divided into 100 equal parts. Celsius is widely used worldwide, especially in scientific contexts, and provides a metric temperature measurement adjusted to water’s physical properties.
Conversion FAQs
Why does the formula subtract 32 before multiplying?
Because Fahrenheit scale zero is 32 degrees higher than Celsius zero, you need to adjust the starting point before scaling the size of one degree. Subtracting 32 aligns the two scales at their zero points, then multiplying by 5/9 converts the unit size.
Can I convert Celsius back to Fahrenheit with this formula?
No, this formula only works from Fahrenheit to Celsius. To convert Celsius to Fahrenheit, multiply by 9/5 then add 32, reversing the adjustment and scaling done in the original formula.
Is the conversion exact or approximate?
The formula gives an exact mathematical conversion between the scales, but practical temperature measurements can have slight errors due to instruments. The decimal places shown often round the result but the formula itself is mathematically precise.
Why does 27°F convert to a negative Celsius number?
Because 27°F is below the freezing point of water (32°F), its equivalent in Celsius falls below zero, resulting in a negative value. Negative Celsius temperatures indicate colder conditions than freezing.
