Milligram (mg)

Definition: A milligram is one thousandth of a gram. It is a very small mass unit used when ingredient quantities are tiny.

History/origin: The milligram comes from the metric system's decimal structure and became useful in nutrition, supplements, and food science.

Current use: Milligrams are used for trace nutrients, additives, supplements, and very small measured quantities.

Ounce (oz)

Definition: The ounce is a customary weight unit used for food portions and ingredients. One avoirdupois ounce converts to approximately 28.35 g.

History/origin: Ounce-based weighing passed from older European trade systems into English and American kitchens, where it stayed common in recipes and retail packaging.

Current use: Oz is often printed on snack bags, cheese blocks, chocolate bars, meat portions, postal-style kitchen scales, and American baking or meal-prep recipes.
