11 degrees Fahrenheit is approximately -11.6667 degrees Celsius.
To convert 11 degrees from Fahrenheit to Celsius, you subtract 32 from the Fahrenheit value, then multiply by 5/9. This shifts the scale to Celsius, which has a different zero point and degree size.

Conversion Formula
The conversion from degrees Fahrenheit to Celsius uses the formula: Celsius = (Fahrenheit – 32) × 5/9. This formula works by first shifting the Fahrenheit value down by 32, which aligns the freezing point of water to zero Celsius. Then, multiplying by 5/9 adjusts for the size difference between the Fahrenheit and Celsius degrees.
Step-by-step for 11°F:
- Subtract 32: 11 – 32 = -21
- Multiply by 5/9: -21 × 5/9 = -105/9
- Simplify: -105/9 ≈ -11.6667°C
Conversion Example
- Convert 50°F to Celsius:
- Subtract 32: 50 – 32 = 18
- Multiply by 5/9: 18 × 5/9 = 90/9 = 10°C
- Convert 0°F to Celsius:
- Subtract 32: 0 – 32 = -32
- Multiply by 5/9: -32 × 5/9 = -160/9 ≈ -17.7778°C
- Convert 100°F to Celsius:
- Subtract 32: 100 – 32 = 68
- Multiply by 5/9: 68 × 5/9 = 340/9 ≈ 37.7778°C
- Convert -40°F to Celsius:
- Subtract 32: -40 – 32 = -72
- Multiply by 5/9: -72 × 5/9 = -360/9 = -40°C

Conversion Definitions
Degrees: Degrees are units used to measure angles or temperature. In temperature, degrees refer to intervals on a scale, like Fahrenheit or Celsius, representing how hot or cold something is. Each degree marks a step between fixed points on the scale.
Celsius: Celsius is a temperature scale where 0 degrees represents the freezing point of water and 100 degrees the boiling point at sea level. It divides the temperature range between freezing and boiling into 100 equal parts called degrees Celsius.
Conversion FAQs
Why do we subtract 32 when converting Fahrenheit to Celsius?
Because the Fahrenheit scale has its zero at a different temperature than Celsius, subtracting 32 shifts the point of freezing water from 32°F to 0°C. This adjustment aligns the two scales before adjusting for degree size differences.
Can the formula give negative Celsius temperatures?
Yes, when Fahrenheit values are below 32, the conversion results in negative Celsius values. This reflects temperatures below freezing point in Celsius, like 11°F converting to approximately -11.67°C.
Is the conversion formula exact or an approximation?
The formula is exact for converting Fahrenheit to Celsius because it comes from the precise relationship between the two scales. However, results might be rounded when displayed, affecting decimal precision.
Why multiply by 5/9 in the formula?
Multiplying by 5/9 scales the temperature difference from Fahrenheit degrees to Celsius degrees. Fahrenheit degrees are smaller; 9 Fahrenheit degrees equal 5 Celsius degrees, so the ratio 5/9 converts between the units properly.
Can this conversion be reversed easily?
Yes, to convert Celsius back to Fahrenheit, multiply by 9/5 and then add 32. This reverses the original formula, shifting zero points and scaling degrees accordingly.
