What is the Fahrenheit equivalent of 15 degrees Celsius?

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

F = (C × 9/5) + 32.

In this case, you would take 15 degrees Celsius and plug it into the formula:

F = (15 × 9/5) + 32

F = (15 × 1.8) + 32

F = 27 + 32

F = 59.

This calculation shows that 15 degrees Celsius is equivalent to 59 degrees Fahrenheit, making this option the correct choice. This conversion is crucial for understanding temperature in different scales, often used in both scientific contexts and in everyday applications, such as weather reports.
