Pears are a naturally sweet, fiber-rich fruit, but they also contribute to your daily potassium intake. This pear potassium calculator estimates the potassium content of pears based on how you typically eat them — by whole fruit size, grams, sliced cups, or ounces.
Because potassium is important for blood pressure regulation, muscle function, and fluid balance, knowing your intake from fruits like pears can support smart meal planning and nutrition tracking. Simply enter the amount you plan to eat, select the serving unit that matches your portion, and the calculator will show milligrams of potassium, the percentage of your daily value, and the math used behind the result.
This tool uses standard USDA nutrition data for raw pears, so the estimate is useful for diet tracking, general meal planning, or just satisfying curiosity about a healthy snack.

How to Use the Pear Potassium Calculator
The tool is designed to be flexible, so you can match the calculator to the way you actually eat pears.
- Enter a number in the amount field.
- Select the unit that matches your portion: small, medium, or large whole pear; grams; cups of sliced pear; or ounces.
- Choose a daily value reference if you want to see your portion as a percentage. The US FDA daily value for potassium is 4700 mg, while the EU uses 2000 mg and the UK uses 3500 mg.
- Click Calculate potassium to see the milligram amount, percentage of daily value, and a step-by-step breakdown.
Quick-select buttons let you jump straight to common amounts, such as one medium pear or 100 g, which is useful when you are entering the same snack repeatedly into a food log.
How the Potassium Estimate Is Calculated
The calculation is based on the USDA nutrient database value for raw pears: approximately 116 mg of potassium per 100 g. That is equal to 1.16 mg per gram, so the tool converts your serving unit into grams and then multiplies by 1.16.
For example, when you select “medium pear” (about 178 g), the calculation is 1 × 178 × 1.16 = 206.5 mg, which rounds to 207 mg of potassium.
For the daily value percentage, the calculator divides the potassium in your portion by the reference value you selected and multiplies by 100. Because pears are a moderate source of potassium — neither very high nor negligible — they fit comfortably into a balanced diet for most healthy adults. You can verify the underlying nutrient values directly in the USDA FoodData Central database if you want to explore variety-specific or brand-specific numbers.
Worked Examples
Example 1: One medium pear
Amount = 1, unit = medium pear (178 g).
1 × 178 g × 1.16 mg/g = 206.5 mg potassium.
Against a 4700 mg daily value that is 4.4% of your DV.
Example 2: 150 g serving, US daily value
150 × 1.16 = 174 mg potassium.
174 ÷ 4700 × 100 = 3.7% of the daily value.
Example 3: Two large pears
2 large pears × 230 g = 460 g.
460 × 1.16 = 533.6 mg potassium, about 11.4% of a 4700 mg daily value.
These examples show how the same fruit can give a very different potassium contribution depending on portion size, which is why weighing or measuring pears is more accurate than estimating by eye.
Pear Potassium Reference Table
| Serving | Approx. weight | Potassium |
|---|---|---|
| 1 small pear | 148 g | 172 mg |
| 1 medium pear | 178 g | 206 mg |
| 1 large pear | 230 g | 267 mg |
| 100 grams | 100 g | 116 mg |
| 1 cup sliced | 140 g | 162 mg |
| 1 ounce | 28.35 g | 33 mg |
Compared to bananas (about 358 mg per 100 g), pears provide roughly one-third the potassium per gram, but they are still a useful, lower-calorie way to add variety and dietary fiber. If you track potassium from different produce, our cherry potassium calculator can help you compare another fruit.
Factors That Affect Accuracy
Potassium content in pears is not perfectly constant. The values above are averages from the USDA nutrient database, and the actual amount in a single pear can vary for several reasons:
- Variety: Bartlett, Bosc, Anjou, and Asian pears have slightly different water, sugar, and mineral profiles. Most varieties are close to the average, but the difference can be a few milligrams per 100 g.
- Ripeness and growing region: Soil potassium, fertilizer use, harvest timing, and storage can all influence mineral content to some degree.
- Portion measurement: Whole pear sizes vary widely by variety and season. A “medium” pear might weigh anywhere from 160 g to 200 g. Weighing your pear gives the most accurate result.
- Skin and preparation: If you peel the pear, the total potassium is slightly lower because some minerals are concentrated under or in the skin. This calculator assumes the pear is eaten with its skin.
Frequently Asked Questions
Are canned pears as high in potassium?
Canned pears are usually packed in syrup, juice, or water, and the packing liquid dilutes the fruit by weight. Potassium values for canned pears are often lower—roughly 60–90 mg per 100 g depending on the product—so always check the nutrition label for the exact figure.
Can I use this calculator for Asian pears?
Asian pears are crisp and contain more water, so their potassium is usually around 120–130 mg per 100 g, close to the value used here. The estimate will still be reasonable, but for precise tracking, weighing the fruit is the best approach.
How much potassium do I actually need per day?
Guidance varies by country. The US FDA uses 4700 mg as the daily value for potassium, while the EU uses 2000 mg and the UK recommends 3500 mg for adults. Your personal needs may be higher or lower depending on age, health conditions, and medications. The NIH Potassium Fact Sheet is a reliable starting point for more detail.
