Temperature conversion is a fundamental concept in physics and chemistry, and it's essential to understand how to convert between different temperature scales. One of the most common conversions is from Fahrenheit to Celsius, and in this article, we'll explore how to convert 78 degrees Fahrenheit to Celsius. To start, let's establish the formula for converting Fahrenheit to Celsius, which is: °C = (°F - 32) × 5/9. This formula will be the foundation of our conversion process.
Understanding the Fahrenheit and Celsius Scales

The Fahrenheit scale is a temperature scale that was developed by Gabriel Fahrenheit in the early 18th century. It’s based on a scale where the freezing point of water is 32 degrees and the boiling point is 212 degrees. On the other hand, the Celsius scale is a more modern temperature scale that was developed by Anders Celsius in the mid-18th century. It’s based on a scale where the freezing point of water is 0 degrees and the boiling point is 100 degrees. Understanding the differences between these two scales is crucial for accurate temperature conversion.
The Conversion Process
To convert 78 degrees Fahrenheit to Celsius, we can use the formula mentioned earlier: °C = (°F - 32) × 5⁄9. Plugging in the value of 78 degrees Fahrenheit, we get: °C = (78 - 32) × 5⁄9. Simplifying the equation, we get: °C = 46 × 5⁄9. Multiplying 46 by 5, we get 230, and then dividing by 9, we get 25.56. Therefore, 78 degrees Fahrenheit is equal to 25.56 degrees Celsius.
| Temperature (Fahrenheit) | Temperature (Celsius) |
|---|---|
| 78 | 25.56 |
| 32 | 0 |
| 212 | 100 |
