Half-and-half is a homogenized blend of equal parts whole milk and light cream, with a fat content of roughly 10–12%. Its density of 1.023 g/ml sits between whole milk (1.031 g/ml) and cream — the fat lowers density slightly relative to straight milk. A cup weighs approximately 242 g; a tablespoon weighs about 15.1 g. As a pourable liquid, it measures reliably by volume: a cup is a cup regardless of temperature, though chilled half-and-half pours more slowly. Used in coffee, cream-based sauces, soups, and as a lighter substitute for heavy cream in custards and pancake batters.

Dairy products (milk, cream, yogurt, cheese) have different fat and water percentages. Volume hides these differences; weight keeps sauces, batters, and doughs consistent.
Fat content shifts density; pick the correct milk/cream/fat level if variants exist.
For cheese, shredded vs grated vs cubed changes volume—prefer grams.
Does fat percentage matter?Yes. A cup of heavy cream is heavier than milk; swapping without weight alters richness and texture.
FAQ
Why does half-and-half weigh less per cup than whole milk?
Half-and-half (1.023 g/ml) is slightly less dense than whole milk (1.031 g/ml) because its higher fat content — roughly 10–12% vs. 3.25% in whole milk — reduces the overall density. Fat has a lower density than water, so richer dairy products are proportionally lighter per unit volume.
Can I substitute half-and-half for heavy cream by weight?
By gram weight, the substitution is structurally sound for most soups and sauces, but the result will be thinner and less rich. Half-and-half (1.023 g/ml, ~242 g/cup) is slightly denser than heavy cream but with far less fat — recipes relying on fat for emulsion or whipping will not behave the same.
How many grams is a tablespoon of half-and-half?
At 1.023 g/ml, one tablespoon (14.79 ml) of half-and-half weighs approximately 15.1 g. This is indistinguishable from a tablespoon of whole milk (15.2 g) for any practical cooking or baking calculation.
