Understanding the Fahrenheit and Celsius Scales
What Is the Fahrenheit Scale?
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724. It is primarily used in the United States and a few other regions. The scale is based on three key points:
- 0°F: The temperature of a mixture of ice, water, and salt.
- 32°F: The freezing point of water.
- 96°F: Originally believed to be the human body temperature (later refined).
The scale is divided into 180 equal parts between the freezing and boiling points of water, which are 32°F and 212°F respectively.
What Is the Celsius Scale?
The Celsius scale, also known as the centigrade scale, was created by Anders Celsius in 1742. It is widely used around the world, especially in scientific contexts. Its key points are:
- 0°C: The freezing point of water.
- 100°C: The boiling point of water at standard atmospheric pressure.
The Celsius scale divides the temperature range between these points into 100 equal parts, making it straightforward for scientific calculations and everyday use.

Converting 82 Fahrenheit to Celsius
The Conversion Formula
To convert Fahrenheit to Celsius, you can use the following formula:
\[
°C = (°F - 32) \times \frac{5}{9}
\]
Applying this formula to 82°F:
\[
°C = (82 - 32) \times \frac{5}{9}
\]
Calculating step-by-step:
1. Subtract 32 from 82:
\[
82 - 32 = 50
\]
2. Multiply by 5:
\[
50 \times 5 = 250
\]
3. Divide by 9:
\[
\frac{250}{9} \approx 27.78
\]
Thus, 82°F is approximately 27.78°C.
Approximate Temperature in Celsius
Rounding to two decimal places, 82°F ≈ 27.78°C.
This temperature is considered warm, typical of late spring or early summer days in many regions.

Comparing Temperature Scales: Fahrenheit vs Celsius
Key Differences
The two scales differ not only in their numerical values but also in their origins and usage:
- The Fahrenheit scale is based on human-related points (like body temperature) and mixtures.
- The Celsius scale is based on water's phase changes, making it more scientific and universally adopted.
Conversion Table for Common Temperatures
Here's a quick reference for some common temperatures in both scales:
- 0°F ≈ -17.78°C (Freezing point of a saltwater mixture)
- 32°F = 0°C (Freezing point of water)
- 68°F ≈ 20°C (Room temperature)
- 82°F ≈ 27.78°C (Warm day)
- 100°F ≈ 37.78°C (High fever or hot day)
- 212°F = 100°C (Boiling point of water)
