Correct option is C
To convert Celsius to Fahrenheit, the formula used is: °F = (°C × 9/5) + 32. Applying this: (40 × 9/5) + 32 = 72 + 32 = 104°F. This formula is essential in clinical settings, especially in nursing and healthcare, for interpreting patient temperature across different units used globally.
Explanation of options: (a) 102 – This is incorrect. When applying the formula, 102°F corresponds to approximately 38.9°C, not 40°C. Hence, it doesn't match the conversion. (b) 103 – This value is slightly closer but still incorrect. It represents around 39.4°C, which is lower than 40°C. (c) 104 – This is the correct answer. The accurate conversion of 40°C to Fahrenheit is 104°F using the standard formula. This is the value nurses and doctors use in clinical documentation. (d) 105 – This is an overestimate. 105°F would correspond to approximately 40.6°C, which is higher than the given temperature.
