1 Cup Raspberries in Grams

1 cup of raspberries weighs 123 g (spooned and levelled, USDA). Delicate, tart-sweet berries. All the figures on this page are approximate conversions based on the USDA value, so when a recipe really matters, verify with a kitchen scale.

Why weighing raspberries beats measuring it in cups

Raspberries are light per cup at 123 g, because they are hollow: each berry is a cluster of tiny drupelets around an empty centre, and a cup of raspberries holds a surprising amount of air. That hollowness is why raspberries are so delicate and why they crush under the slightest pressure, and it is also why the cup measure is unreliable for them. A cup of raspberries handled gently weighs less than a cup of raspberries pressed down, because pressing crushes the berries and removes the air, so the same cup can weigh 20 g more or less depending on how it was filled.

The fragility is the second reason to weigh raspberries rather than measuring them. Rinsing, drying and tipping them into a cup all risk crushing them, and crushed raspberries release juice that changes the weight and stains the batter. The reliable approach is to weigh the berries in their punnet on the scale, tare the scale, and tip them gently into the bowl. The USDA figure of 123 g per cup is medium confidence, which reflects the variation in berry size and ripeness, so treat it as a guide and trust your own scale for the berries you actually have.

1/4 cup 30.8 g 4
1/3 cup 41 g 5.3
1/2 cup 61.5 g 8
2/3 cup 82 g 10.7
3/4 cup 92.2 g 12
1 cup 123 g 16

2 cups 246 g 32
3 cups 369 g 48
4 cups 492 g 64

One tablespoon of raspberries weighs about 7.7 g, since a cup is 16 tablespoons. That is useful when a recipe calls for a spoonful or two rather than a whole cup, though for small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one.

Worked examples

Raspberry and white chocolate muffins, a batch of 12

A batch of 12 muffins uses about 1 1/2 cups of raspberries, which is 185 g, folded into the batter with white chocolate chips. Weigh the berries gently in their punnet, then fold them in last with two strokes so they stay whole. Tossing them in a spoonful of flour first stops them sinking, and weighing matters because crushed berries weigh more per cup than whole ones, so a cup measured roughly can be 20 g heavy.

Raspberry sauce for a cheesecake

A sauce for one cheesecake uses about 2 cups of raspberries, which is 246 g, simmered with 50 g of sugar and a squeeze of lemon until the berries collapse, then sieved. Weigh 246 g before cooking, because the sauce reduces and the starting weight decides the final yield. Sieving removes the seeds and leaves a smooth, bright sauce that sets off the richness of the cheesecake.

Raspberry salad topping for six

A salad for six people uses about 1 cup of raspberries, which is 123 g, scattered over mixed leaves with goat cheese and toasted nuts. Add the berries at the last moment so they do not bleed juice into the leaves, and weigh them in the punnet so they are not crushed by tipping them into a measuring cup. Because raspberries are light, a cup looks like a generous amount, and cooks who measure by eye tend to use too many.

How the weight was measured

The figure on this page comes from USDA, measured spooned and levelled unless the method line says otherwise. Spooning means filling the cup with a spoon rather than plunging the cup into the bag, and levelling means sweeping a knife across the rim. Scooping packs the ingredient down and can add a fifth or more to the weight, which is why two bakers following the same cup-based recipe can get visibly different results.

Confidence in this value is medium. That reflects how consistent the ingredient is from brand to brand: a uniform, factory-packed ingredient is more predictable than a fresh, variable one. Even a high-confidence figure is still an approximation, because moisture, grind size and settling all shift the weight a little. Treat the grams on this page as a reliable starting point and check with a scale when the recipe is fussy, expensive, or being made for the first time.

Practical guidance

Refrigerate raspberries and use them within 2 days, because they are the most perishable berry and mould spreads quickly from one bad berry to the next. Pick out any soft or mouldy berries before measuring, and rinse them very gently just before use, drying them on a tea towel. Weigh the berries in their punnet on a tared scale rather than tipping them into a measuring cup, which crushes them and changes the weight. When baking with raspberries, fold them in last with as few strokes as possible, and expect them to bleed a little colour: that is normal and the flavour is worth it. If you do not have a scale, fill the cup very gently without pressing down and remember the 123 g figure is approximate and medium confidence.

Common mistakes with fresh fruit

The most common mistake is measuring fruit by the cup before preparing it. A cup of whole strawberries and a cup of sliced strawberries are different weights, because slicing removes air gaps, so always prepare the fruit first, then measure, and weigh whenever the recipe is precise. The second mistake is using under-ripe or over-ripe fruit without adjusting: unripe fruit is lighter, firmer and less sweet, while very ripe fruit is heavier and wetter, and both change the batter. The third is washing berries and measuring them while they are still wet, which adds water weight and throws off the balance. Dry them gently before measuring. Finally, do not fold delicate berries into a thick batter with a heavy hand: they burst, bleed colour through the crumb, and sink. Fold once or twice, gently, and dust them with a spoonful of flour first so they stay suspended.

Frequently asked questions

How many grams is 1 cup of raspberries?

1 cup of raspberries weighs 123 g when spooned and levelled, according to the USDA. The figure is medium confidence and approximate, because the hollow berries crush easily and berry size varies, so verify with a kitchen scale when it matters.

Why are raspberries so light per cup?

Because each raspberry is a hollow cluster of tiny drupelets around an empty centre, so a cup of raspberries holds a lot of air. The berries are also delicate and crush easily, which changes the weight depending on how they are handled.

How many cups is 100 g of raspberries?

100 g of raspberries is about 0.81 cups, or just over 3/4 cup. At 123 g per cup, divide 100 by 123 to get the answer, and use a scale for the most accurate result.

Can I use frozen raspberries in baking?

Yes, and they are often better than fresh for baking, because they hold their shape until they hit the heat. Use them straight from the freezer, expect the batter to need a minute or two longer in the oven, and do not thaw them first or they will bleed colour everywhere.

How do I stop raspberries sinking in muffins?

Toss the berries in a spoonful of flour before folding them in, use a thicker batter, and fold them in last with only a couple of gentle strokes. Weighing the berries also helps, because an overloaded batter cannot hold the fruit up.
