Mentioned on Behind the Bastards recently. Had to find the ad.
500 degrees? WTF.
Wiki page here: https://en.wikipedia.org/wiki/Human_bake_oven
You would think, but no. It was Fahrenheit. They rarely (if ever) went to 500 F though.
Look at the newspaper article: https://lemmy.zip/post/68972958/28002374 edmonton was canada, and they didnt start using metric for temp until the 70's I think.
Also the wikipedia article says this as well. Its F!
