They do suck but CTA stops in Chicago have these and they’re better than nothing in the brutal cold. A lifesaver when the train is going to take a while

Sure, but just dress warmly with another layer. The reason they’re a waste is because the vast majority of actual heat energy is just lost to the atmosphere.

Brother I don’t think you understand how cold Chicago gets. I was wearing 2 sweaters and a coat and it’s still fucking cold as balls

Similar deal in Canada. It’s bitter hell waiting for a bus or train in -40c even with as many layers on as you can fit. These heaters are absolutely worth the energy use

That’s -40f for those south of the border.

No need to thank me for doing all that math. On a serious note, some actually helpful points are:

0c = 32f (probably the most well known one)

10c = 50f

20c = 68f

30c = 86f

40c = 104f

Aside that, I figure I’ll be cooking and therefore using a nice enough thermometer to have both scales. Otherwise things have gone terribly, terribly wrong, and I have much larger problems to worry about than conversions.
