Convert 100.8 F to Celsius: _ C (round to nearest tenth)
The Correct Answer and Explanation is:
To convert 100.8°F to Celsius, we use the following formula:
[
°C = (°F – 32) \times \frac{5}{9}
]
Substitute the value of 100.8°F:
[
°C = (100.8 – 32) \times \frac{5}{9}
]
[
°C = 68.8 \times \frac{5}{9}
]
[
°C = 68.8 \times 0.5556
]
[
°C ≈ 38.2
]
So, 100.8°F is approximately 38.2°C when rounded to the nearest tenth.
Explanation:
Temperature conversions between Fahrenheit (°F) and Celsius (°C) are common in scientific and medical fields, especially in nursing where accurate measurements are crucial for patient care. Fahrenheit is primarily used in the United States, while Celsius is the standard for most of the world and is used in scientific contexts. Knowing how to convert between these units is essential for understanding vital signs, like body temperature.
The conversion formula involves subtracting 32 from the Fahrenheit value because 0°C corresponds to 32°F, a baseline difference between the two scales. After subtracting 32, the remaining Fahrenheit degrees are adjusted to the Celsius scale by multiplying by 5/9 (approximately 0.5556). This accounts for the fact that each degree on the Celsius scale represents a larger temperature difference than each degree on the Fahrenheit scale, which is why we scale down by a factor of 5/9.
For example, a fever is typically recognized when a person’s body temperature exceeds 100.4°F. Converting this threshold to Celsius ensures proper interpretation in global healthcare contexts, where the equivalent is approximately 38°C. In this case, 100.8°F corresponds to 38.2°C, indicating a mild fever, which would prompt further clinical evaluation.
Accurate conversions are vital in ensuring consistent care across different healthcare systems, preventing errors when monitoring patient conditions.
