Cups of heavy cream to grams

What the sources say about a cup of heavy cream

Two published sources, side by side. Where a source lists several forms or ways of measuring, each is a row.

Spread across sources: 5% between USDA and King Arthur for the main entry. Ingredient weights vary by brand, packing and humidity; the table is a reference, not a guarantee.

Why this number: 238 g per US cup

We use the USDA measured weight, because for liquids, fats, syrups and free-flowing grains a measured weight is more reliable than a rounded ounce value. Where the two sources disagree, both figures are in the table above and in the calculator, so you can switch to the one your recipe was written with.

Liquid heavy cream weighs 238 g a cup by USDA (15 g per tablespoon); King Arthur rounds to 227 g (8 oz) for heavy cream, light cream and half-and-half alike. USDA also gives a second, very different cup: whipped cream at 120 g, because whipping roughly doubles the volume. A recipe that says "1 cup whipped cream" is asking for about half as much cream weight as "1 cup cream, whipped".

As a rough guide, 1 cup of liquid cream whips to about 2 cups (USDA states this yield), though it depends on the fat content and temperature.

UK double cream (about 48% fat) and US heavy cream (about 36 to 40%) are not identical; for conversion purposes their weights per cup are close.

Grams of heavy cream to cups

US cup, metric cup and spoons

One US cup of heavy cream at our default weight is 238 g. A 250 ml metric cup, used in Australia, New Zealand, Canada and many metric recipes, holds the same volume plus 5.7%, which is 251 g. A US legal (nutrition label) cup of 240 ml is 241 g. These all assume the same packing as the US cup; read about it on US cup vs metric cup.

Sources and when they were checked

• USDA FoodData Central, SR Legacy (April 2018 release), food Cream, fluid, heavy whipping (FDC ID 170859). Gram weights per household measure as published; per-cup figures where USDA lists a different amount (such as 2 tablespoons) are scaled.
• King Arthur Baking, Ingredient Weight Chart, row(s): Cream (heavy cream, light cream, or half & half). Chart rows that list a quarter cup, half cup or tablespoon are scaled to a full cup on this page; the original listing is shown in the table above.
• Cup volumes: the US customary cup is exactly 236.5882365 ml; the US nutrition-label cup is defined in US law as 240 ml (21 CFR 101.9); the metric cup is 250 ml (see US cup vs metric cup).

Last checked 27 October 2026. Weights are for reference: ingredients vary by brand, humidity and how they are packed. If your recipe gives gram weights, use those.
