To convert 42 degrees Celsius to Fahrenheit, we use the formula: Fahrenheit = (Celsius * 9/5) + 32. Substituting 42 for Celsius, we get Fahrenheit = (42 * 9/5) + 32. First, we calculate 42 * 9, which equals 378. Then, we divide 378 by 5, resulting in 75.6. Finally, we add 32 to 75.6, which gives us 107.6 degrees Fahrenheit.
Understanding the Conversion Process
The conversion from Celsius to Fahrenheit involves a simple mathematical operation. The formula takes into account the different zero points and scales of the two temperature scales. The Celsius scale sets the freezing point of water at 0 degrees and the boiling point at 100 degrees, while the Fahrenheit scale sets these points at 32 and 212 degrees, respectively. This difference necessitates the multiplication by 9⁄5 and the addition of 32 to convert from Celsius to Fahrenheit.
Application of the Conversion Formula
For any given temperature in Celsius, we can apply the formula directly. For example, to convert 0 degrees Celsius (the freezing point of water) to Fahrenheit, we substitute 0 for Celsius in the formula, resulting in (0 * 9⁄5) + 32 = 32 degrees Fahrenheit. This confirms that 0 degrees Celsius is equivalent to 32 degrees Fahrenheit. Similarly, to convert 100 degrees Celsius (the boiling point of water) to Fahrenheit, we substitute 100 for Celsius, getting (100 * 9⁄5) + 32 = 212 degrees Fahrenheit, confirming that 100 degrees Celsius is equivalent to 212 degrees Fahrenheit.
| Temperature in Celsius | Equivalent in Fahrenheit |
|---|---|
| 0 | 32 |
| 42 | 107.6 |
| 100 | 212 |

Temperature conversions are a fundamental aspect of physics and are used in a wide range of applications. From scientific research to cooking and weather forecasting, being able to convert between different temperature scales is a valuable skill. The conversion from Celsius to Fahrenheit, in particular, is commonly required due to the widespread use of both scales in different parts of the world. By applying the formula or using a conversion table, one can easily switch between these two scales.
Why are there different temperature scales?
+The different temperature scales, such as Celsius and Fahrenheit, were developed historically for various reasons, including the materials available for thermometer construction and the need for a scale that could accurately measure a wide range of temperatures. The Celsius scale, for example, was designed to have 100 degrees between the freezing and boiling points of water, making it a more intuitive scale for scientific applications.
How do I convert Fahrenheit to Celsius?
+To convert Fahrenheit to Celsius, you use the inverse of the Celsius to Fahrenheit formula: Celsius = (Fahrenheit - 32) * 5⁄9. This formula rearranges the original to solve for Celsius, allowing you to convert temperatures from Fahrenheit to Celsius.
What is the most commonly used temperature scale today?
+The Celsius scale is the most commonly used temperature scale in the world today, especially in scientific and technical applications. However, the Fahrenheit scale is still widely used in the United States for everyday applications, such as weather forecasting.
