Hello sire!
That does seem like an odd problem!
There's multiple things that could've happened, but with the provided information I can't tell you much.
Do you have more information about this maybe? Accidental click on a purchase, or perhaps you bought Imperial units instead of the regular ones? Let me know when remembered something!
Perhaps it's a good time to check this article while I look for more information regarding this issue for you!
I'm sorry for the inconvenience!
Edit: It appears this concern was asked and answered before! Please, check this topic for more information!
