Understanding Temperature Scales: Fahrenheit and Celsius
What is Fahrenheit?
Fahrenheit (°F) is a temperature scale primarily used in the United States and some Caribbean countries. It was developed by Daniel Gabriel Fahrenheit in the early 18th century. The scale is based on three fixed points:
- The freezing point of water at 32°F
- The boiling point of water at 212°F
- The zero point, which was originally based on a mixture of ice, water, and salt
The Fahrenheit scale is known for its finer granularity, with 180 degrees separating the freezing and boiling points of water.
What is Celsius?
Celsius (°C), also known as centigrade, is a temperature scale used worldwide, especially in scientific contexts. It was developed by Anders Celsius and is based on the freezing point of water at 0°C and boiling point at 100°C under standard atmospheric pressure.
Why Convert Between Fahrenheit and Celsius?
Conversions are necessary because different regions and scientific disciplines use different scales. Knowing how to switch between Fahrenheit and Celsius allows for:
- Accurate weather interpretation
- Proper cooking temperatures
- Scientific data analysis
- International travel planning

How to Convert 11°F to Celsius
The Conversion Formula
The standard formula to convert Fahrenheit to Celsius is as follows:
Celsius (°C) = (Fahrenheit (°F) - 32) × 5/9
Applying this formula to 11°F:
C = (11 - 32) × 5/9
Step-by-Step Conversion Process
1. Subtract 32 from the Fahrenheit temperature:
- 11 - 32 = -21
2. Multiply the result by 5/9:
- -21 × 5/9 = -105/9
3. Simplify the fraction:
- -105 ÷ 9 ≈ -11.6667
Therefore, 11°F is approximately -11.67°C.
