Metric or Imperial? (Revisited) (Again)

I can remember a time when product reviewers would stick to one measurement system. If the backpack volume was measures in cubic inches, the weight of the backpack was measured in pounds and ounces.

That sort of consistency seems to have flown out of the window with Boulder, Colorado-based Skiing magazine measuring backpack weights in ounces and backpack volumes in liters/litres.

Will the US ever go fully metric? It is slowly creeping in. I'd give it another 20- years or so.
