One pound of plums is usually 6 to 8 medium plums, depending on size. A medium raw plum is listed at 66 grams in the USDA SNAP-Ed seasonal produce guide for plums, so fruit size changes the count quickly.
For recipes, the more useful conversion is volume after prep: 1 pound of whole plums yields 2½ to 3 cups pitted sliced or chopped plums. Use the calculator and chart below as practical kitchen guides, and weigh the fruit when accuracy matters for baking, jam, sauces, or preserves.
Plum conversion calculator
Enter pounds, plums, cups, grams, or quarts to estimate how much fruit to buy and how much prepared plum you will have.
Calculator assumptions: 1 pound equals about 6 to 8 medium plums, 2½ to 3 cups pitted sliced or chopped plums, or 453.6 grams. A quart of whole plums is estimated at about 1½ pounds because packing space changes by size.
Plum conversion chart
The USDA Food Buying Guide fruit yield table lists 1 pound of raw plums as about 2⅔ cups ready-to-serve unpeeled, pitted fruit for 2-inch plums and about 2⅞ cups pitted fruit for 2½-inch plums. That supports the practical kitchen range of 2½ to 3 cups, depending on size and how the fruit is cut.
Whole-plum weight includes the pits. Cup measurements should be based on pitted edible fruit.

How many plums in a pound?
A pound of plums is usually 6 to 8 medium plums. If the plums are large, you may only need 4 to 5. If they are small oval Italian prune plums, it can take closer to 8 to 12 pieces to reach a pound.
Counting plums is useful when shopping, but weight is more reliable for recipes. Round plums can look similar in a produce bin and still vary enough in weight to change the final amount of sliced fruit.
If you are buying plums for a seasonal dessert or sauce, it also helps to know when plums are in season, since ripe summer plums are usually juicier and easier to prep.
Plum size and weight chart
Plum size is the main reason the count changes. Use this chart as a kitchen estimate, then weigh the fruit if the recipe depends on a precise amount.
| Plum size | Typical weight each | Plums per pound |
|---|---|---|
| Small plums | 40 to 55 grams | 8 to 12 |
| Medium plums | 60 to 75 grams | 6 to 8 |
| Large plums | 90 to 115 grams | 4 to 5 |
| Italian prune plums | Often smaller and oval | 8 to 12, depending on size |
Chef note: For baking and preserves, sliced cups are helpful, but weight is steadier. A cup of thin plum slices can settle differently than a cup of thick wedges, especially when the fruit is very ripe and juicy.
How many plums in a cup?
One cup of sliced or chopped plums usually takes 2 to 3 medium plums. Smaller plums may take more pieces, while large plums may need fewer.
- 1 cup sliced plums: 2 to 3 medium plums
- 1 cup chopped plums: 2 to 3 medium plums, depending on dice size
- 1 pound pitted plums: 2½ to 3 cups sliced or chopped
For the cleanest recipe conversion, pit and slice the plums before measuring. Whole plums leave too much empty space in a cup to be a reliable volume measurement.
How many plums in a quart?
A quart equals 4 cups. For whole plums, that usually works out to 9 to 12 medium plums, depending on fruit size and how loosely the plums are packed.
Quart measurements are most useful when buying, packing, or storing fresh plums. For cooking, weight or pitted sliced cups will give you a more predictable result.
Measuring tips for recipes
- Use weight for accuracy: A pound of plums is more reliable than a plum count, especially for baking and preserves.
- Pit before measuring cups: Cup measurements should be based on edible fruit, not whole plums with pits.
- Slice or chop first: Cut size changes how tightly the fruit fits into the cup.
- Watch ripeness: Very ripe plums are softer and juicier, so diced fruit can settle more tightly.

Plum measurement FAQs
For 4 cups of sliced or chopped plums, plan on about 8 to 12 medium plums. That is roughly 1⅓ to 1½ pounds of whole plums, depending on size, ripeness, and how thickly the fruit is cut.
Use whole weight when shopping, but measure cups after pitting. Pits are included in the pound when you buy plums, while cup measurements in recipes usually mean edible sliced or chopped fruit.
Use the count and cup ranges as a practical estimate. One pound is usually 6 to 8 medium plums, and 1 cup sliced or chopped is usually 2 to 3 medium plums. For jam, preserves, and baking recipes with tight ratios, a scale is still the better choice.
Yes. Small plums may take 8 to 12 pieces per pound, while large plums may take only 4 to 5. That is why a range is more useful than one exact number.
A quart container usually holds about 9 to 12 medium whole plums, which is often more than a pound. If a recipe gives a pound measurement, weigh the fruit or use about 6 to 8 medium plums as the closer estimate.
