The process of converting temperature from Fahrenheit to Celsius is a common task in various fields, including science, medicine, and everyday life. To convert 100.4 F to Celsius, we use the formula: Celsius = (Fahrenheit - 32) * 5/9. Applying this formula to 100.4 F, we first subtract 32 from 100.4, which gives us 68.4. Then, we multiply 68.4 by 5/9, which equals 38.0. Therefore, 100.4 F is equivalent to 38.0 Celsius.
Understanding the Conversion Formula
The conversion formula from Fahrenheit to Celsius is based on the fact that the freezing point of water is 32 degrees Fahrenheit and 0 degrees Celsius, and the boiling point of water is 212 degrees Fahrenheit and 100 degrees Celsius. The formula utilizes these reference points to establish a linear relationship between the two temperature scales. The coefficient of 5⁄9 is derived from the ratio of the differences between these reference points in the two scales, ensuring that the conversion is accurate and consistent.
Practical Applications of Temperature Conversion
In medical contexts, converting between Fahrenheit and Celsius is crucial for accurately monitoring body temperature, which is a key indicator of health. For instance, a body temperature of 100.4 F, as mentioned, is equivalent to 38.0 Celsius, which may indicate a mild fever. In scientific research, precise temperature control and measurement are essential, and being able to convert between different temperature scales is a fundamental skill. Moreover, in everyday life, understanding temperature conversions can be useful when traveling to countries that use the metric system or when following recipes that list temperatures in Celsius.
| Temperature in Fahrenheit | Equivalent Temperature in Celsius |
|---|---|
| 32 F | 0 C |
| 100.4 F | 38.0 C |
