Easy
Convert 40 degree celsius to Ferenheit
Appeared in: BHU NO-2019
Explanation
- The formula to convert Celsius (°C) to Fahrenheit (°F) is F = (C × 9/5) + 32.
- First, multiply the Celsius temperature by 9/5 (or 1.8): 40 × 1.8 = 72.
- Next, add 32 to this result: 72 + 32 = 104.
- Thus, 40°C is equivalent to 104°F.
Why Other Options Were Wrong
- Option A: This is an incorrect calculation. It does not follow the standard conversion formula.
- Option B: This value is close to the normal human body temperature (98.6°F or 37°C), but it is not the correct conversion for 40°C. A temperature of 40°C indicates a high-grade fever.
- Option C: This is an incorrect calculation. The number 100 is significant as the boiling point of water in Celsius, not a Fahrenheit conversion value in this context.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Temperature conversion from Celsius to Fahrenheit as background academic context rather than a clinical decision trigger.
- Accurate temperature conversion is a fundamental skill in nursing to correctly assess a patient's condition, especially when documenting vital signs or communicating with healthcare teams that may use different scales.
- A temperature of 40°C (104°F) is considered a high-grade fever (pyrexia) and is clinically significant. It indicates a strong immune response or a serious underlying condition that requires prompt medical evaluation and management.
- What if? If a patient's temperature was 104°F and you needed to document it in Celsius for a specific protocol, you would use the reverse formula: C = (F - 32) × 5/9. This would be (104 - 32) × 5/9 = 72 × 5/9 = 40°C.
How to Approach the Question
- First, identify the task: The question asks to convert a temperature from Celsius to Fahrenheit.
- Recall the correct formula for this conversion: F = (C × 9/5) + 32. A simple way to remember is 'Multiply by 1.8 and add 32'.
- Substitute the given value (40) for 'C' in the formula.
- Perform the calculation: (40 × 1.8) + 32 = 72 + 32 = 104.
- Compare your calculated result with the given options.
- Select the option that matches your result, which is 104.
