Kahuna,
Food quantities started shrinking the day Canada went metric, shaving ml's or mm's off of every consumable on the grocery shelves.
Biggest scam ever perpetrated on a North American populace.
' Hey ! I know! Let's clip about a hundred milliliters off the little juice box thingies, and make a fuggin' bundle in gross product output. They'll never notice.'
The thing about pounds and ounces is you can't fuk with 'em , or else they're not pounds and ounces anymore.
I dunno if you were alive before Metric came to Canada, but it wasn't as sleazy..
