To convert 49 degrees Fahrenheit to Celsius, we use the formula: °C = (°F - 32) × 5/9. Substituting 49 for °F, we get: °C = (49 - 32) × 5/9. First, subtract 32 from 49, which equals 17. Then, multiply 17 by 5, resulting in 85. Finally, divide 85 by 9, which gives us 9.44 degrees Celsius. Therefore, 49 degrees Fahrenheit is equivalent to approximately 9.44 degrees Celsius.
Understanding the Conversion Process
The conversion from Fahrenheit to Celsius involves a simple mathematical formula. However, understanding the history and application of these temperature scales can provide deeper insight. The Fahrenheit scale was introduced by Gabriel Fahrenheit in 1724, while the Celsius scale, originally known as the centigrade scale, was introduced by Anders Celsius in 1742. The Celsius scale is based on the freezing and boiling points of water, making it a more intuitive system for scientific applications.
Practical Applications of Temperature Conversion
In everyday life, converting between Fahrenheit and Celsius is crucial for various activities, such as cooking, where recipes may list temperatures in either scale, or in weather forecasting, where temperature is a key factor. For instance, knowing that 49 degrees Fahrenheit is roughly 9.44 degrees Celsius can help in planning outdoor activities based on the weather forecast. Moreover, in scientific research, precise temperature control and conversion are vital for experiments and data analysis.
| Temperature (Fahrenheit) | Temperature (Celsius) |
|---|---|
| 32 | 0 |
| 212 | 100 |
| 49 | 9.44 |

Why is temperature conversion important?
+Temperature conversion is crucial for ensuring accuracy and consistency across different applications and regions, facilitating international communication and collaboration.
What are the reference points for temperature conversion?
+The key reference points are the freezing point of water (32°F or 0°C) and the boiling point of water (212°F or 100°C), which serve as the basis for converting between the Fahrenheit and Celsius scales.
How does the formula for converting Fahrenheit to Celsius work?
+The formula °C = (°F - 32) × 5⁄9 subtracts the freezing point of water from the given Fahrenheit temperature, then applies the scaling factor to convert the result into Celsius, effectively aligning the two scales.
