Maple syrup is prized for its rich flavor, but when you are tracking protein, its label can be confusing. Most nutrition labels list protein in grams per serving — such as 0.3 g per 30 ml — rather than per 100 g, which is the standard used in food databases, meal planners, and compare tools. This calculator converts any label value to a protein-per-100g figure, so you can compare maple syrup against other sweeteners and log your macros accurately.
Whether you are meal-prepping, following a high-protein diet, or simply curious about the nutritional profile of real maple syrup, this tool works with any label you have. Enter the serving size and protein per serving from the package, choose how much syrup you actually ate (in grams or tablespoons), and optionally set your daily protein target. The calculator then shows the protein content per 100 g, the protein in your portion, and how much of your daily target that portion covers.
Use it alongside other per-100g nutrition tools to get a consistent picture of your intake.

Step-by-Step Guide
To use this calculator, look at the nutrition facts panel on your bottle of maple syrup. You need two numbers: the serving size in grams (sometimes the label gives millilitres — convert by using 1 ml ≈ 1.32 g for pure maple syrup) and the protein amount listed under that serving. Many brands round protein down to 0 g, but larger servings can contain 0.1–0.5 g. For most calculations, rounding to 0 is acceptable because maple syrup is not a meaningful protein source, but the tool lets you enter the exact label value if one is shown.
Next, enter the amount of syrup you plan to eat or drink. You can type it in grams or select tablespoons; the calculator converts US tablespoons to grams using 20 g per tablespoon. Then set your daily protein target if you want the percentage breakdown. Press Calculate to see the result.
The Label Math: How the Conversion Works
The calculation is straightforward:
Protein per 100 g = (protein per serving ÷ serving size in g) × 100
Because the per-100g value is a density — grams of protein per 100 g of food — you can scale it to any portion size. The portion protein is then:
Protein in portion = (protein per 100 g ÷ 100) × portion weight in g
For example, if a label says a 30 g serving contains 0.4 g protein, the protein per 100 g is (0.4 ÷ 30) × 100 = 1.33 g. If you eat 45 g of syrup, your protein intake is (1.33 ÷ 100) × 45 = 0.60 g.
Worked Example
Scenario: A bottle of maple syrup states: serving size 30 g, protein 0.3 g. You drizzle 1.5 tablespoons (30 g) over pancakes and set a daily protein target of 70 g.
- Protein per 100 g = (0.3 ÷ 30) × 100 = 1.00 g
- Portion weight = 1.5 tbsp × 20 g/tbsp = 30 g
- Protein in portion = (1.00 ÷ 100) × 30 = 0.30 g
- Share of daily target = (0.30 ÷ 70) × 100 = 0.43%
That tiny amount shows why maple syrup is usually treated as a carbohydrate-only food for macro planning.
Reference: Protein in Common Maple Products
For context, here are approximate protein values per 100 g for common maple-based foods. Always check your specific brand, because formulations vary.
| Product | Protein per 100 g (approx.) |
|---|---|
| Pure maple syrup (USDA generic) | 0.04 g |
| Light maple syrup (typical label) | 0.0–0.1 g |
| Maple-flavored syrup | 0.0–0.2 g |
| Maple sugar (dried syrup) | 0.1 g |
| Maple butter (creamed syrup) | 0.04 g |
The table reflects that maple syrup is nearly all carbohydrate; any protein present is negligible for daily needs. If your label shows exactly 0 g, the per-100g result will simply be 0 g.
Common Questions
Is maple syrup a significant source of protein?
No. Even the purest maple syrup contains only trace protein, usually under 0.1 g per 100 g. It is essentially a concentrated sugar source, providing energy but very few other macronutrients.
Why do some labels show 0 g protein?
Food labeling regulations allow values below 0.5 g per serving to be rounded to 0. If a serving is small (e.g., 30 g), the true protein may be 0.1–0.4 g but omitted. The per-100g calculation from the rounded label will then underestimate actual protein slightly.
Can I use this calculator for honey or agave?
Yes — the math is identical for any food. Just enter the serving size and protein from the label. For sweeteners, protein is typically very low, but the same per-100g conversion works.
How accurate is the tablespoon conversion?
One US tablespoon equals about 14.8 ml; pure maple syrup has a density around 1.32–1.37 g/ml, so one tablespoon weighs roughly 20 g. If you use a kitchen scale, weigh your syrup in grams for the best accuracy.
Tips for Accurate Protein Tracking
Weigh before you pour. Syrup is sticky and dense; volume measurements like tablespoons are fine for rough logging, but a digital scale gives you the true grams and avoids overpouring.
Use the per-100g value in your food app. Most nutrition databases store values per 100 g. The result from this tool matches that format, making it easy to input into MyFitnessPal, Cronometer, or similar apps.
Don't rely on syrup for protein. If you're increasing protein intake, focus on protein-dense foods and use maple syrup only as a flavoring. For accurate calorie and macro comparisons, you can also check a maple syrup calorie per 100 g breakdown.
Because maple syrup contributes almost no protein, the main planning decision is usually portion size and calories, not protein. Still, knowing the exact per-100g value lets you keep every macro honest in your log.
