That isn't the greatest example of that IMO. From what I've read, the real problem there wasn't just imperial/metric confusion, it was the fact that the team providing data did not provide any units at all, and the team receiving the data didn't ask and just assumed units.

One of the first things I was taught in engineering school was to always provide units! It doesn't matter if you're only using metric; that still doesn't tell you if it's a gram or a kilogram, after all.
