What will make the change easier is smartphones, smart-phone measuring stick can tell you cm. I haven't seen one but I assume a smartphone could also be used to measure weight?
If I'm placing bets, the liter will be the metric unit to take over next in the USA (winning out over gallon and fl. oz), maybe just because the gallon has a good size, not too small or too large - stuff you buy liquid is often around 0.5 - 2 liters.
