Oat milk is a plant drink made by blending oats with water and straining out the solids, prized for its creamy mouthfeel and slight natural sweetness. One metric cup (250 ml) weighs around 245 grams or 8.64 ounces. When a recipe calls for oat milk in cups but the carton lists millilitres, converting by weight keeps the body of coffee, porridge, and dairy-free bakes consistent.

Oat milk cartons hold 1 litre or 250 ml mini-packs, while recipes call for cups, grams, and tablespoons. Converting between the four stops you over-pouring into a delicate batter.
