My son, getting up for work this morning….

@Matt85 celsius

@Matt85
Below -40 degrees, Celsius and Fahrenheit remain identically the same as each other.

@SW-User For realzies?.. They the same at that level?

@Matt85
Yes, for sure. As Fahrenheit and Celsius decline in value below their respective freezing points (32F/ 0C), the temperature scales of both converge and finally intersect each other at -40 degrees F and C.

@SW-User Ah right. Confusing.🤪

@Matt85
Very true! The temperature scales when placed side by side, actually form a 'V' shape, where at the bottom of the V, both are the same at -40.

But as you go up in temperature, both scales diverge away from each other forming that 'V' shape, where +40 degrees Celsius is now 104 degrees Fahrenheit.

@Matt85 🤔.............- 48C is -54F

@Jimmy2016 so its about the same, like she said?

@Matt85 Yep.........-40C = -40F

@Jimmy2016 Okay. Glad we established that.

@SW-User Below -40 they diverge again.

@NudasPriest
That is correct. As I previously stated, both scales converge and finally intersect each other at -40 degrees F and C.
