What is 39.4 °C in °F?
The Correct Answer and Explanation is :
To convert Celsius to Fahrenheit, you can use the following formula:
[
°F = \left(°C \times \frac{9}{5}\right) + 32
]
Substituting 39.4°C into the formula:
[
°F = \left(39.4 \times \frac{9}{5}\right) + 32
]
First, multiply 39.4 by 9, which gives 354.6. Then, divide this by 5, resulting in 70.92. Finally, add 32 to this value:
[
°F = 70.92 + 32 = 102.92°F
]
So, 39.4°C is approximately 102.92°F.
Explanation
Temperature is measured on different scales, primarily Celsius (°C) and Fahrenheit (°F). Celsius is commonly used worldwide, while Fahrenheit is predominantly used in the United States and a few other countries. Understanding the conversion between these scales is important, especially in fields like healthcare, meteorology, and engineering.
The Celsius to Fahrenheit conversion involves multiplying by (\frac{9}{5}) (or 1.8), which adjusts for the difference in the scaling between the two units. The Celsius scale is based on the freezing (0°C) and boiling (100°C) points of water, whereas the Fahrenheit scale sets 32°F as the freezing point and 212°F as the boiling point of water.
In healthcare, accurate temperature conversion is essential. A body temperature of 39.4°C is considered a fever and converting it to Fahrenheit (102.92°F) helps to interpret it in systems that use this scale. For example, a fever over 100.4°F (38°C) often indicates an infection or illness. Recognizing such details is important for patient care and decision-making.
Understanding this conversion ensures consistent communication, particularly in globalized settings, where both temperature scales might be in use.
