Converting can sizes in old recipes: PROBLEM SOLVED!

I've been making some family-favorite recipes in anticipation of the holiday season, and two in the last two days have called for old can sizes, as in "Add a #2 can of crushed pineapple".  The internet, which steered me so cruelly wrong on how much ground coffee to add to a vintage percolator (thanks for helping out, IowaSue!), looks to be more reliable this time.  This info comes from the Iowa State University Extension website.
