Convert 101.2° F Into Centigrade?

Appeared in: NORCET 2 -2021 (Shift-2)

Explanation

The standard formula to convert temperature from Fahrenheit (°F) to Celsius (°C) is: °C = (°F - 32) × 5/9.
First, substitute the given value of 101.2°F into the formula: °C = (101.2 - 32) × 5/9.
Perform the subtraction within the parentheses: 101.2 - 32 = 69.2.
Next, multiply this result by 5/9: 69.2 × 5/9 = 346 ÷ 9.
The final calculation yields approximately 38.44°C.
Among the given options, 38.4°C is the correct conversion.

Option A: This is an incorrect calculation. It may result from an arithmetic error during the multiplication or division steps of the conversion formula.
Option C: This value is significantly lower than the correct conversion and represents a substantial calculation error. A temperature of 37.4°C is closer to the upper limit of the normal range.
Option D: This is an incorrect calculation. This value is only slightly above the normal body temperature range and does not correspond to a fever of 101.2°F.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Temperature conversion from Fahrenheit to Celsius as background academic context rather than a clinical decision trigger.
Accurate temperature conversion is a fundamental skill for nurses to correctly assess a patient's condition, as a temperature of 101.2°F (38.4°C) indicates a low-grade fever that requires monitoring.
Different healthcare settings or devices may use different scales (Fahrenheit or Celsius), so nurses must be proficient in converting between them to ensure accurate documentation and communication.
What if the patient's temperature was 98.6°F? Applying the same formula, the Celsius equivalent is 37°C, which is the standard for normal human body temperature. This highlights the importance of knowing key reference points.

How to Approach the Question

Step 1: Identify the task, which is to convert a temperature from Fahrenheit (°F) to Celsius (°C).
Step 2: Recall the correct mathematical formula for this conversion: °C = (°F - 32) × 5/9.
Step 3: Substitute the given Fahrenheit value (101.2) into the formula.
Step 4: Perform the calculation in the correct order of operations: first subtract 32, then multiply by 5, and finally divide by 9.
Step 5: Compare your calculated result to the given options to find the correct answer.
