Cups of raisins to grams

What the sources say about a cup of raisins

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

Spread across sources: 3% 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: 149 g per US cup

We use King Arthur's published figure, which is a stated reference for home bakers and is the weight most gram-based recipes from that source use. 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.

USDA gives 145 g for a loose cup of raisins and 165 g packed. King Arthur gives 149 g loose and 170 g packed. The two sources agree within 3%, and both show the same packed-versus-loose gap of about 14%.

Raisins that have dried out and hardened pack differently from fresh ones and weigh the same by gram but not by cup. Soaking them first changes the weight and the volume.

Sultanas and golden raisins are treated as equivalent in USDA's table (same 145 g and 165 g).

Grams of raisins to cups

US cup, metric cup and spoons

One US cup of raisins at our default weight is 149 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 157 g. A US legal (nutrition label) cup of 240 ml is 151 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 Raisins, dark, seedless (Includes foods for USDA's Food Distribution Program) (FDC ID 168165). 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): Raisins (loose), Raisins (packed). 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.
