What happens if you make a mistake in unit of order

(1)Hey, you crazy mold guys. Common sense, 65mm doesn’t make sense
(2)You should’ve asked me back at least once when you got the order, you moron
(3)No matter how wrong our mistake is, 65cm is 65mm!

(1)Detective Geum, when would we ever make something like this if it weren’t for this opportunity? It’s not our fault anyway
