A 12 oz can in cups
Cans of soda or evaporated milk are labeled in fluid ounces, which measure volume, so the answer above is the can.
Soda and evaporated milk cans are labeled 12 fl oz, a true volume, so they hold exactly 1½ cups (355 ml). A 12 oz can of solid food, such as corned beef, is labeled by weight instead.
For any can, multiply the servings per container by the serving size on its Nutrition Facts label. Labels round both, and brands differ, so treat these as close, not exact.
