To convert Fahrenheit to Celsius, what is the formula used?

The process of converting Fahrenheit to Celsius is best captured by the formula that appropriately relates the two temperature scales. The correct formula for this conversion is derived from the equation (C = (F - 32) \times \frac{5}{9}), which can also be expressed using the option given. In the context of the options provided, the most relevant conversion approach reflects the manipulation of the variables to yield Celsius from Fahrenheit.

For Celsius to Fahrenheit, the transformation involves taking the Celsius temperature, multiplying by 1.8 (or (\frac{9}{5})), and then adding 32 to accommodate the offset between the two scales. Thus, this specific formula is indicative of the correct methodology used to derive Fahrenheit from Celsius.

Understanding this relationship is crucial in applications involving temperature conversions in pharmacy and healthcare settings, ensuring that medications and treatments based on temperature are accurately administered or documented. This clarity aids in grasping the overall concepts of temperature in relation to pharmaceutical practices, even though the incorrect options either misrepresent the conversions or confuse the sequence of calculations needed for accurate results.
