Why there is no difference between Fahrenheit and centigrade when temperature is minus figure?

Answer 1

The starting point is that 0 Celsius equals 32 Fahrenheit. One degree Celsius is of higher value than one degree Fahrenheit. So, going less than zero on centigrade, the rate of decrease on Celsius is less than the rate of dgress of Fahrenheit until it comes the point of -40 degrees Celsius when both scales match together.

Mathematically,

F = C x 9/5 +32

Where F is degrees Fahrenheit and C degrees Celsius


Accordingly,

-40 degrees Celsius = 32 - 40 x 9/5 = -40 degrees Fahrenheit

Answer 2

At minus figures, the Fahrenheit and Celsius scales converge at -40 degrees, making this temperature equivalent on both scales. This is due to the linear relationship between the two temperature scales, where they intersect at this specific value. Beyond -40 degrees, the difference between Fahrenheit and Celsius temperatures will vary depending on the actual temperature.

Answer 3

To convert from Celsius to Fahrenheit, multiply by 9, divide by 5, and add 32. Therefore, -40 Celsius is equal to -40 x 9 = -360/5 = -72 + 32 = -40 degrees Fahrenheit.

Answer 4

They don't.

They only share one negative value. -40º is the same on both scales.

Answer 5

(-40) degrees Fahrenheit = -40 degrees Celsius.

Answer 6

There is only one temperature where the Fahrenheit and Celsius numbers are the same.

That's -40 degrees.
