So the question is, why would pioneers of aviations US would switch their F measures onto C?
Just curious. Why would they made this headache for their pilots?
Небось что под рукой лежало то и ставили, а головные боли у тогдашних летчиков похлеще этой были.
Translation: they likely just installed whatever instruments they had on hand, and as for headaches, the pilots had bigger things to worry about.
