If a refrigerator is set to 0 degrees Fahrenheit, how cold is that in Degrees Centigrade?

• A. -17.8 degrees Centigrade
• B. -15 degrees Centigrade
• C. -12.5 degrees Centigrade
• D. -10 degrees Centigrade

Answer: (A)

To convert from degrees Fahrenheit to degrees Centigrade (Celsius), you can use the formula: \[ C = \frac{(F - 32) \times 5}{9} \] Where \( F \) represents degrees Fahrenheit. In this case, the temperature is set at 0 degrees Fahrenheit. Plugging in the value: 1. Subtract 32 from 0: \[ 0 - 32 = -32 \] 2. Multiply by 5: \[ -32 \times 5 = -160 \] 3. Divide by 9: \[ \frac{-160}{9} \approx -17.78 \] Rounding to one decimal place gives you approximately -17.8 degrees Centigrade. This calculation confirms that when the refrigerator is set to 0 degrees Fahrenheit, it corresponds to about -17.8 degrees Centigrade, which aligns perfectly with the first choice. This temperature conversion is vital in pharmacy settings, especially for the storage of medications that require specific temperature controls.

To convert from degrees Fahrenheit to degrees Centigrade (Celsius), you can use the formula:

[ C = \frac{(F - 32) \times 5}{9} ]

Where ( F ) represents degrees Fahrenheit. In this case, the temperature is set at 0 degrees Fahrenheit.

Plugging in the value:

1. Subtract 32 from 0:

[

0 - 32 = -32

]

2. Multiply by 5:

[

-32 \times 5 = -160

]

3. Divide by 9:

[

\frac{-160}{9} \approx -17.78

]

Rounding to one decimal place gives you approximately -17.8 degrees Centigrade. This calculation confirms that when the refrigerator is set to 0 degrees Fahrenheit, it corresponds to about -17.8 degrees Centigrade, which aligns perfectly with the first choice. This temperature conversion is vital in pharmacy settings, especially for the storage of medications that require specific temperature controls.
