What is the Celsius equivalent of -40 degrees Fahrenheit?

Explanation:
To convert Fahrenheit to Celsius, you can use the formula: C = (F - 32) × 5/9 Plugging -40 degrees Fahrenheit into this formula gives: C = (-40 - 32) × 5/9 C = (-72) × 5/9 C = -360/9 C = -40 Thus, -40 degrees Fahrenheit is equivalent to -40 degrees Celsius. This unique case occurs because -40 is the point at which the Fahrenheit and Celsius scales intersect, meaning they represent the same temperature value.

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

C = (F - 32) × 5/9

Plugging -40 degrees Fahrenheit into this formula gives:

C = (-40 - 32) × 5/9

C = (-72) × 5/9

C = -360/9

C = -40

Thus, -40 degrees Fahrenheit is equivalent to -40 degrees Celsius. This unique case occurs because -40 is the point at which the Fahrenheit and Celsius scales intersect, meaning they represent the same temperature value.
