What is the Celsius equivalent of 72 degrees Fahrenheit?

To convert degrees Fahrenheit to degrees Celsius, the formula used is:

°C = (°F - 32) × 5/9.

Applying this formula to the conversion of 72 degrees Fahrenheit:

1. Subtract 32 from 72 degrees Fahrenheit:

72 - 32 = 40.

2. Multiply the result by 5/9:

40 × 5/9 ≈ 22.2.

Thus, 72 degrees Fahrenheit is approximately 22.2 degrees Celsius. This calculation confirms that option A provides the correct Celsius equivalent for 72 degrees Fahrenheit. The understanding of this conversion is important in both scientific and everyday contexts when temperature readings are given in different measurement systems.
