11 degrees Fahrenheit is approximately -11.6667 degrees Celsius.
To convert 11 degrees from Fahrenheit to Celsius, the formula subtracts 32 from the Fahrenheit value, then multiplies by 5/9. This adjusts for the different freezing points and scaling used in the two temperature units.

Conversion Formula
The formula to convert degrees Fahrenheit to Celsius is:
Celsius (°C) = (Fahrenheit (°F) – 32) × 5/9
This formula works because Fahrenheit and Celsius scales has different zero points and increments. Fahrenheit sets freezing point of water at 32°F, Celsius at 0°C. Subtracting 32 aligns the zero points, then multiplying by 5/9 converts the scale difference.
For example, converting 11°F:
- Subtract 32: 11 – 32 = -21
- Multiply by 5/9: -21 × 5/9 = -11.6667°C
Conversion Example
- Convert 50°F to Celsius:
- Subtract 32: 50 – 32 = 18
- Multiply by 5/9: 18 × 5/9 = 10°C
- Convert -40°F to Celsius:
- Subtract 32: -40 – 32 = -72
- Multiply by 5/9: -72 × 5/9 = -40°C (notice same value)
- Convert 100°F to Celsius:
- Subtract 32: 100 – 32 = 68
- Multiply by 5/9: 68 × 5/9 = 37.7778°C
- Convert 32°F to Celsius:
- Subtract 32: 32 – 32 = 0
- Multiply by 5/9: 0 × 5/9 = 0°C (freezing point of water)

Conversion Definitions
Degrees: Degrees are units that measure temperature, angles, or geographic coordinates. In temperature, degrees represent intervals on thermometric scales like Celsius or Fahrenheit, indicating how hot or cold something is relative to fixed points like water’s freezing or boiling.
Celsius: Celsius is a temperature scale using degrees as units where 0° marks water’s freezing point and 100° its boiling point at sea level. It’s widely used worldwide for weather, science, and daily temperature readings, providing a decimal-based system for measurement.
Conversion FAQs
Why do we subtract 32 when converting Fahrenheit to Celsius?
Subtracting 32 adjusts the Fahrenheit value to align with Celsius zero point. Since Fahrenheit scale sets freezing water at 32°F, removing that offset makes the temperature relative to freezing point before scaling by 5/9. This step is crucial for accurate conversion.
Can the conversion formula give negative Celsius values?
Yes, temperatures below 32°F will convert to negative Celsius numbers. Since Celsius zero is freezing point and Fahrenheit freezing is 32 degrees, any Fahrenheit value less than 32 results in a negative Celsius after conversion, representing temperatures below freezing.
Is 11 degrees Fahrenheit considered cold in Celsius?
At approximately -11.67°C, 11°F is cold, much below freezing point of water (0°C). This temperature would be freezing cold enough to cause ice and frost in many environments. So, yes, 11°F is cold when expressed in Celsius.
Why use 5/9 in the conversion formula?
The fraction 5/9 represents the ratio of Celsius scale to Fahrenheit scale increments. Fahrenheit degrees are smaller intervals, with 180 increments between freezing and boiling; Celsius has 100 increments. Multiplying by 5/9 scales the difference in unit size accurately.
Is the conversion reversible?
Yes, converting back from Celsius to Fahrenheit uses the reverse formula: Fahrenheit = (Celsius × 9/5) + 32. This reversibility ensures temperature values can be converted both ways maintaining accuracy between the scales.
