To all: I just came home from a local Costco. I was passing through an aisle with toilet paper there. I happened to eavesdrop on a conversation between an elderly couple, which was trying to decide which toilet paper brand to purchase. One was Costco's Kirtland Signature brand and the other one was Charmin. Their choice was to find the one which would have more paper in the pack, since apparently the prices were similar. One had area stated in sq. ft. (m2) and the other one in sq. yds. (m2). Guess how they compared them. That's right, the only common measurement is m2. So, they had no problems comparing the two in SI. This is especially hopeful, because it was my perception, that the elderly will have the hardest time changing over to SI when it happens. Cheers, Nick
