Why don't they just ditch imperial measurements altogether?

Also, that description sounds like tracing a bug through a few layers of software where there wasn't proper error handling along the way, just trusting the data being passed around.

Amusingly, the reason why the confusion was there was because at that time Canada was in the process of converting from the Imperial system to the Metric, but they had to manually convert some things still!
