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.

Cow's milk is richer in fat than oat milk (around 3 to 4% to oat milk's 3%) and slightly heavier (258 g vs 245 g per cup). Swap 1:1 by volume in pancakes, cocoa, and cake batters for a dairy-free result; oat milk gives a thicker mouthfeel in coffee than skim or low-fat milk. See our Milk converter.

Almond milk is thinner and lower in fat than oat milk (around 1 to 2% to oat milk's 3%). They are equal in weight (245 g vs 245 g per cup) and swap 1:1; oat milk gives a creamier body in coffee and bakes, while almond milk stays lighter in shakes and porridge. See our Almond Milk converter.

Soy milk is higher in protein than oat milk (around 3% to oat milk's 1%), so it sets firmer in cooked sauces and custards. They are equal in weight (245 g vs 245 g per cup) and swap 1:1; oat milk wins in coffee for body, while soy milk wins in custards for hold. See our Soy Milk converter.

Oat milk is blended from rolled oats and water, then strained, so the oats are its base ingredient. Soak and blend rolled oats to make your own, and weigh the oats when scaling a batch up or down. See our Rolled Oats converter.
