What's wrong with this?

Auto shade packaging?

Hmmm, looks like somebody slavishly followed the 5/9 + 32 formula (or whatever it is that I was supposed to have learned in the 10th grade, some 55 years ago!).

right, when converting absolute temperatures you have the 32 degree offset.
So if its 44 deg F outside, yes, it's 7 degrees C.
But When comparing temperature DIFFERENCES, the offset drops out and only the 5/9 ratio applies. So lowering the temperature (a difference) 44 deg F is the same as lowering the temperature 24 deg C, not 7.

Another case of knowing a little but not enough is hazardous.

Maybe its a curse, but when I see numbers I want to try and make sense of them. This one rang my bell immediately.

I get a little more than 24.4 C assuming 44 F is correct or 12.6 F assuming 7 C is correct.

I get a little more than 24.4 C assuming 44 F is correct or 12.6 F assuming 7 C is correct.

I'd bet on the second. A 44°F change seems a bit much.

I have the opposite curse: numbers make no sense to me. Ever. Even so, I could tell something was not right with the label.

I agree, Bob.

44 degrees F is possible. a black dashboard in the sun under glass could probably easily reach 150F (in Texas in June) while being shaded could make that dashboard more like 106F...

12.6 deg F is nothing.

I agree, but it might depend on the conditions. Any reduction even if it's 12° is better than no change.
