The Short Answer
So 100 grams of whole almonds is about ⅔ cup, and 250 grams comes to roughly 1¾ cups. That reference number, though, only applies to whole almonds — sliced, slivered, ground, and flour versions each need their own figure, since the shape of the pieces changes how much air sits between them in the cup.

Grams per Cup by Almond Form
This is the table worth bookmarking, since it's the part most generic converters get wrong by treating all "almonds" as one ingredient:
| Almond Form | Grams per Cup | Ounces per Cup |
|---|---|---|
| Whole almonds | 143 g | 5.0 oz |
| Coarsely chopped almonds | ~135 g | 4.8 oz |
| Slivered almonds | 108 g | 3.8 oz |
| Sliced almonds | 92 g | 3.3 oz |
| Ground almonds (home-processed) | 100–125 g* | 3.5–4.4 oz |
| Almond flour (packaged, blanched) | ~96 g | 3.4 oz |
| Flaked almonds | ~75 g | 2.6 oz |
*Ground almonds show the widest spread of any form here, and it's worth explaining why rather than pretending there's one exact number. How fine you grind them, whether the skins are left on, and how much oil has been released during processing (almonds are fatty enough that over-processing turns them into almond butter) all shift the weight. If you're grinding your own, weighing the result once and noting your own number is more reliable than any generic chart — including this one.
Why the Numbers Vary So Much Between Forms
Every almond form is really the same nut with a different amount of trapped air around it:
Whole almonds are smooth, oval, and roll into fairly tight contact with each other, which is part of why they pack the heaviest per cup among the sliced/chopped/slivered group.
Slivered almonds (thin, elongated strips) leave narrow gaps between pieces — enough air that a cup weighs noticeably less than whole almonds.
Sliced almonds are flatter and thinner than slivers, which paradoxically leaves more open space per cup, making them the lightest of the "cut" forms.
Flaked almonds are cut even thinner still, closer to shavings, so they trap the most air of any cut form and land at the low end of the scale.
Ground almonds and almond flour should, in theory, be the densest — fine particles usually pack tighter. But almonds are oily, so fine grinding can cause slight clumping rather than settling perfectly flat, which is part of why this category has the widest real-world range.
Grams to Cups Chart (Whole Almonds)
| Grams | Cups | Ounces |
|---|---|---|
| 28 g | ~⅕ cup | 1 oz |
| 36 g | ¼ cup | 1.3 oz |
| 57 g | ~⅖ cup | 2 oz |
| 72 g | ½ cup | 2.5 oz |
| 100 g | ~0.7 cup | 3.5 oz |
| 107 g | ¾ cup | 3.8 oz |
| 143 g | 1 cup | 5 oz |
| 200 g | ~1.4 cups | 7.1 oz |
| 250 g | ~1.75 cups | 8.8 oz |
| 454 g (1 lb) | ~3.17 cups | 16 oz |
| 500 g | ~3.5 cups | 17.6 oz |
Tablespoons and Ounces, for Smaller Amounts
Since almonds are frequently used a handful or a spoonful at a time — toppings, garnishes, small recipe additions — here's the same conversion at a finer scale, based on whole almonds:
| Amount | Grams |
|---|---|
| 1 tablespoon | ~8.9 g |
| 2 tablespoons | ~17.8 g |
| ¼ cup (4 tbsp) | ~36 g |
| 1 oz | ~28 g |
| 4 oz | ~113 g |
| 8 oz (½ lb) | ~227 g |
| 16 oz (1 lb) | ~454 g |
Does Packing the Cup Change the Weight?
Yes, and almonds are a good example of why "spoon and level" matters as an instruction, not just a suggestion. A gently filled, leveled cup of sliced or slivered almonds sits close to the reference numbers above. Shake the cup, tap it on the counter, or press the almonds down, and the pieces settle into each other's gaps more tightly — which can push the weight up by as much as 20–25% over a loosely filled cup. This effect is stronger for cut almond forms (sliced, slivered, chopped) than for whole almonds, simply because cut pieces have more irregular edges that can nest together when compacted.
Whole, Sliced, or Slivered — Can You Substitute One for Another?
Not without adjusting the amount, and not always successfully in terms of texture. If a recipe calls for sliced almonds and you only have slivered, swapping by cup measurement is closer to correct than swapping by piece count, but you'll still get a different mouthfeel — slivered almonds are thicker and crunchier, while sliced almonds are thinner and toast faster. Whole almonds can't sensibly substitute for either without chopping them first. Ground almonds and almond flour are close enough to interchange in many recipes, though flour is generally more finely and evenly processed, which matters in delicate baked goods like macarons.
A Few Things Worth Knowing About Almonds Beyond the Conversion
- Toasting changes flavor, not weight. Raw, blanched, and toasted almonds can be substituted for each other in equal amounts by cup or weight — toasting mainly deepens the flavor and helps almonds stay suspended in batter instead of sinking during baking.
- Bitter almonds aren't sold in the US. The almonds found in grocery stores are the sweet variety; bitter almonds contain a compound that's toxic when raw and are restricted from sale in the US, showing up instead in small, processed amounts in some European extracts and almond paste.
- Almond flour and ground almonds aren't quite the same product. Commercial almond flour is typically made from blanched (skin-off) almonds ground very finely and evenly. Home-ground almonds — especially with skins left on — tend to be coarser and slightly heavier per cup as a result.
- Store almonds in the fridge or freezer for freshness. Almonds have a relatively high fat content for a nut, which means they can turn rancid faster than shelf-stable pantry staples if left at room temperature for extended periods.
Quick Reference
- 36 g whole almonds = ¼ cup
- 72 g whole almonds = ½ cup
- 143 g whole almonds = 1 cup
- 108 g slivered almonds = 1 cup
- 92 g sliced almonds = 1 cup
- 96 g almond flour = 1 cup
The Bottom Line
There's no single "grams per cup" answer for almonds — the form matters as much as the amount. Whole almonds pack the densest at around 143 g/cup, cut forms like sliced and slivered sit noticeably lighter, and ground almonds or almond flour fall somewhere in between depending on how finely they're processed. When a recipe specifies a form, use that form's number rather than a generic almond average, and when precision really counts — macarons, financiers, anything where almond flour affects structure — weigh rather than scoop.
Other Ingredients
Grams-to-cups conversion isn't only useful for almonds. Each of these has its own weight-per-cup because densities differ:
