OZ to ML

Oz to Ml conversion. Many liquid items are sold in ounce containers. Milk, for example, can be sold in 16-ounce cartons. That amount of milk gives you 298 calories, 25 grams of carbs, and 15 grams of protein. Did you notice that we also used grams as the unit of measure for the carbs and protein? That’s because most people in the world understand the concept of a gram. It’s part of the more systematic metric system.

The use of ounce, on the other hand, is part of the more problematic English system of measurement. To add to the confusion, the ounce measurement is used for precious metals and bullion coins. It’s called troy ounce. But this time, there are 480 grains to 1 troy ounce! Are you confused yet? Don’t worry, most people have found this too complicated. It’s why they now use the more sensible metric system of milliliters and liters instead.
