Can Sizes and Equivalents
(Common Can Sizes)

Q. Is it true that once a canned food has been opened, it is unsafe to store the unused portion in the can?
A. According to the National Food Processors Association, storing food in an opened can does not pose a health risk if it remains covered. But acidic foods may erode the inside of the can once exposed to the air and create a metallic-tasting product.

This chart will come in handy to determine how much to buy. Many recipes specific a can size rather than a volume size. This chart will help you when substituting in a recipe.
