0 °F is equal to what temperature in Celsius?

To convert a temperature from Fahrenheit to Celsius, you can use the formula:

[

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

]

In this case, substituting 0 °F into the formula gives:

[

C = \frac{5}{9}(0 - 32)

]

This simplifies to:

[

C = \frac{5}{9}(-32)

]

Calculating this yields:

[

C = -\frac{160}{9}

]

which is approximately -17.78 °C, often rounded to -18 °C. Therefore, the correct conversion of 0 °F is equal to approximately -18 °C, making this choice accurate. Understanding this conversion is essential in various fields, including refrigeration, where temperature scales may be used interchangeably. It’s important to ensure precise conversions to maintain system efficiency and safety in refrigeration operations.
