Maple syrup is more than a breakfast topping — it contains a small but measurable amount of potassium, along with other minerals like calcium and zinc. This calculator estimates the potassium in any amount of pure maple syrup, whether you measure by tablespoon, cup, milliliter, or grams, using nutrient data from USDA FoodData Central.
Each calculation uses standard US kitchen conversions and a typical maple syrup density of 1.33 g/mL, so the reported mass matches the amount you actually pour or weigh. You can switch between volume and weight units at any time, and quick presets make common portions one click away.
The result panel shows milligrams of potassium, the percentage of the 4,700 mg Daily Value, and a banana-equivalent comparison so you can judge the number in everyday terms. Athletes, meal planners, and anyone tracking potassium for health reasons can use the tool to keep portions realistic.

Calculation breakdown
How to Use This Tool
Start by choosing the unit that matches the way you are measuring. The default is tablespoons because that is how most people pour maple syrup over pancakes, waffles, or oatmeal. Enter the amount as a decimal if needed — 1.5, 0.25, or 3.75 all work — and press Calculate potassium. If you are weighing your portion on a kitchen scale, switch the unit to grams and enter the weight shown; this gives the most direct and accurate result because it skips assumptions about density.
The quick preset buttons at the top are a convenient shortcut. Clicking 2 tbsp, ½ cup, or 100 g fills in the amount and unit and runs the calculation immediately, so you can compare typical serving sizes. After each calculation, the result panel shows the potassium in milligrams, the mass of syrup, the percentage of the 4,700 mg Daily Value, the banana equivalent, and the volume in US cups. A short step-by-step breakdown explains how each number was derived. Use the Reset button to clear everything and start fresh.
Formula Explained
The potassium estimate is built from two standard conversions. First, when you enter a volume, the tool converts it to milliliters using US kitchen equivalents: 1 tsp = 4.92892 mL, 1 tbsp = 14.7868 mL, 1 fl oz = 29.5735 mL, 1 cup = 236.588 mL. It then converts milliliters to grams with the density of maple syrup, 1.33 g per milliliter. If you enter grams, no volume conversion is needed.
The nutrient factor comes from USDA FoodData Central, which reports about 212 mg of potassium per 100 g of pure maple syrup. That equals 2.12 mg per gram. Once the mass in grams is known, the potassium is simply:
Potassium (mg) = mass (g) × 2.12
For the Daily Value percentage, divide by 4,700 mg and multiply by 100. For the banana comparison, divide by 422 mg, the approximate potassium content of a medium banana. These two benchmarks help you place a maple syrup portion in the context of your overall potassium intake.
Worked Examples
Reference Table: Common Portions
The table below summarizes typical values for popular serving sizes using the same USDA average and 1.33 g/mL density. Actual numbers on a specific bottle may differ slightly.
| Portion | Approx. volume | Mass | Potassium | % DV |
|---|---|---|---|---|
| 1 tsp | 4.9 mL | 6.6 g | 14 mg | 0.3% |
| 1 tbsp | 14.8 mL | 19.7 g | 42 mg | 0.9% |
| 2 tbsp | 29.6 mL | 39.3 g | 83 mg | 1.8% |
| ¼ cup | 59.1 mL | 78.7 g | 167 mg | 3.5% |
| ½ cup | 118.3 mL | 157.3 g | 333 mg | 7.1% |
| 1 cup | 236.6 mL | 314.7 g | 667 mg | 14.2% |
| 100 g | 75.2 mL | 100 g | 212 mg | 4.5% |
Tips & Best Practices
- Weigh when precision matters. A food scale removes density variability. Volume measurements are fine for everyday tracking, but grams are the gold standard.
- Read the label on your bottle. The USDA average is a general guide; your producer’s nutrition panel may list a specific potassium value. When the two disagree, use the label for your exact product.
- Don’t confuse real maple syrup with pancake syrup. Maple-flavored table syrups are mostly corn syrup, water, and flavoring, and their potassium content can be much lower than pure maple syrup.
- Keep sugar in perspective. Maple syrup contains roughly 52 g of sugar per 100 g. A potassium benefit does not make it a free food, especially for people watching carbohydrate intake.
- Check personal targets. The 4,700 mg DV is a general reference. People with kidney disease or those taking certain medications may have different potassium goals, so follow the advice of your healthcare provider.
Frequently Asked Questions
Is the potassium in maple syrup significant? It is modest. A typical 2-tablespoon serving provides about 83 mg, which is 1.8% of the Daily Value. That is much less than a banana (about 422 mg), a cup of cooked spinach, or a medium potato, but it still counts toward your daily total.
Why do different bottles have different nutrition numbers? Potassium in maple syrup comes from the soil and the tree, so it varies by region, season, and individual sugar bush. The syrup is also boiled to a standardized density, but trace minerals are not added or removed. USDA values are an average across many samples.
Does organic grade affect potassium? No. Organic certification concerns farming practices — no synthetic chemicals in the sugarbush — not the mineral content of the sap. The tree’s uptake of potassium from soil is the main factor, not the label.
Can I use this tool for maple cream, maple butter, or maple sugar? Only approximately. Maple cream contains less water and more sugar per spoonful, while maple sugar is even more concentrated, so the potassium per gram is higher. The tool is calibrated for liquid maple syrup. For the most reliable numbers, use the nutrition label on the specialty product.
