Cherries are one of the most popular summer fruits, and they also deliver a surprising amount of potassium — a mineral that helps regulate fluid balance, nerve signals, and muscle contractions. If you track micronutrients for general wellness or plan meals around a potassium-sensitive diet, this calculator takes the guesswork out of portion math.
Enter the amount of cherries you plan to eat, choose a unit — grams, ounces, cups, or whole cherries — and select the type: sweet, tart, or dried. The calculator then shows how many milligrams of potassium your portion provides and what share of the daily value that represents. It also displays the gram-weight conversion so you can verify every step.
The estimates are based on standard USDA nutrition data for raw and dried cherries. Use the whole-cherry setting for a quick snack estimate, or choose grams for the closest accuracy when you weigh your food on a kitchen scale.

How to Use This Tool
Choose the amount of cherries you want to analyze with the calculator above. For the most accurate result, weigh the fruit on a kitchen scale and enter grams; this avoids the natural size variation of whole cherries. If you don't have a scale, use the cups or whole-cherry shortcuts — the calculator applies standard reference weights for sweet, tart, and dried cherries. After you choose the cherry type, click Calculate Potassium to see the total milligrams and the percentage of the daily value based on a 4,700 mg reference. The step-by-step breakdown underneath shows the converted weight and the potassium density used, so you can double-check every number.
How the Potassium Calculation Works
The calculator uses a simple proportion based on USDA nutrient data:
Potassium (mg) = weight in grams × potassium per 100 g ÷ 100
For example, fresh sweet cherries contain about 222 mg of potassium per 100 g. A 138 g cup therefore provides 138 × 222 ÷ 100 = 306 mg. To convert the result into a daily value percentage, the tool divides by the adult reference value for potassium (4,700 mg per day) and multiplies by 100.
The weight-to-volume estimates used for cups and whole cherries are reference standards from nutrition databases. Since cherries vary with variety, size, and water content, gram weights are always the most reliable input.
Worked Examples
- 1 cup sweet cherries: 138 g × 222 ÷ 100 = 306 mg potassium, about 6.5% DV.
- 4 oz tart cherries: 4 × 28.35 = 113.4 g; 113.4 × 173 ÷ 100 = 196 mg, about 4.2% DV.
- 20 whole sweet cherries: 20 × 8.2 = 164 g; 164 × 222 ÷ 100 = 364 mg, about 7.7% DV.
- 60 g dried cherries: 60 × 402 ÷ 100 = 241 mg, about 5.1% DV.
Tips for Accurate Tracking
Use the same source of nutrition data consistently. The USDA FoodData Central database is a good reference for plain fresh fruit. When a packaged product label lists potassium per serving, that label value should take priority over a generic calculator because brands differ.
Cherry Potassium Reference Table
| Cherry Type | Potassium (mg / 100 g) | Approx. Weight per Cup | Potassium per Cup |
|---|---|---|---|
| Sweet, raw | 222 | 138 g | 306 mg |
| Tart, raw | 173 | 155 g | 268 mg |
| Dried | 402 | 160 g | 643 mg |
Frequently Asked Questions
Is the potassium daily value always 4,700 mg? The FDA's Daily Value for potassium is 4,700 mg for adults and children age 4 and older. Some countries use 3,500 mg as a dietary target, so the percent DV on this calculator is based on the U.S. labeling standard.
Can I use this for frozen cherries? Plain frozen cherries without added sugar have similar potassium to fresh fruit per 100 g, but freezing can change water content slightly. The generic values here are reasonable for fresh and unsweetened frozen cherries.
Why does the calculator ask about tart versus sweet? Tart (sour) cherries naturally contain less potassium than sweet cherries. If you use the wrong type, your estimate can be off by roughly 20–30 mg per 100 g, which matters when tracking potassium carefully.
Do cherry pits affect the calculation? The weight values in the calculator refer to the edible portion after the pit is removed. If you weigh whole cherries with pits, subtract roughly 8–12% of the weight for typical pit mass, or weigh the pitted fruit directly.
