Definition: A metric cup is a volume unit equal to exactly 250 milliliters.
History/origin: The metric cup was adopted in countries that preferred a clean metric kitchen measure while still keeping the familiar idea of a cup.
Current use: Metric cups are used in Australia, New Zealand, Canada in some contexts, and modern metric-adapted recipes.
Definition: The ounce is a customary weight unit used for food portions and ingredients. One avoirdupois ounce converts to approximately 28.35 g.

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.
