Snack chips are rarely celebrated for protein, but protein per 100 grams is one of the clearest ways to compare chip brands and decide whether a snack fits your daily macro targets. This calculator takes the serving size and protein amount printed on any chip nutrition label and converts them into a standard protein-per-100g value. It works for potato chips, tortilla chips, pita chips, veggie chips, lentil chips, and any other packaged snack.
You can enter the serving weight in grams or ounces, add the protein per serving, and the calculator will normalize everything to 100 grams. If you also enter the number of servings per package, you will see the total protein in the whole bag or box. That makes it easy to spot the difference between a small high-protein snack and a large bag with only modest protein.
This tool is useful for anyone counting macros, following a higher-protein eating plan, or just checking whether a new chip product earns a place in their snack rotation.

This calculator is for general nutrition estimates only; always rely on the label on your actual product.
Quick Start: Reading a Chip Label
Start by looking at the Nutrition Facts panel on your chip bag. Find the serving size, which is usually given in both grams (g) and a household measure such as “about 11 chips” or “1 oz.” Then find “Protein” lower in the label; this is the amount of protein in one serving. Enter those two numbers in the calculator above, choose grams or ounces, and press Calculate.
How the Protein-per-100g Calculation Works
Chip brands use different serving sizes, which makes raw label numbers hard to compare. Normalizing to 100 grams solves this by turning every product into the same “how much protein is in a 100 g portion” question. The formula is simple:
Protein per 100 g = (Protein per serving ÷ Serving size in grams) × 100
If your serving size is in ounces, first multiply by 28.3495 to get grams. For example, a 1.5 oz serving equals 1.5 × 28.3495 = 42.52 g. Then divide the protein by that gram weight and multiply by 100. This is the same math used by food databases to list nutrient density per 100 g.
Worked Examples
Example 1 — Classic potato chips: Serving size 28 g, protein 2 g. (2 ÷ 28) × 100 = 7.14 g protein per 100 g.
Example 2 — Pita chips: Serving size 28 g, protein 4 g. (4 ÷ 28) × 100 = 14.29 g protein per 100 g.
Example 3 — Tortilla chips in ounces: Serving size 2 oz (56.7 g), protein 4 g. (4 ÷ 56.7) × 100 = 7.05 g protein per 100 g.
What Makes Some Chips Higher in Protein
The base ingredient matters more than the flavor. Standard potato chips and corn tortilla chips are made from starchy vegetables or corn, which have limited protein naturally; most contain about 5–8 g per 100 g after cooking. Chips made from wheat flour, such as pita chips and baked crackers, tend to be a little higher, often 9–14 g per 100 g. Bean-based and lentil-based chips can reach 12–20 g per 100 g because legumes are naturally protein-rich. Seasonings contribute only a tiny amount—a few tenths of a gram—unless they include cheese or yeast-based flavorings.
Reference Protein Ranges for Common Chip Types
The table shows approximate typical values, not exact label data. Check your own bag.
| Chip type | Typical protein per 100 g | Notes |
|---|---|---|
| Classic potato chips | 5–8 g | Most brands are in this range. |
| Kettle-cooked potato chips | 6–8 g | Similar to classic, slightly higher from thicker slices. |
| Tortilla chips | 6–8 g | Corn-based, moderate protein. |
| Pita chips | 10–14 g | Higher due to wheat flour. |
| Veggie chips | 2–6 g | Often mostly potato flour or starch. |
| Cheese puffs | 5–7 g | Protein from cheese powder is small. |
| Lentil or bean chips | 12–20 g | Highest plant-protein option. |

Frequently Asked Questions
Why do chip labels show “2 g protein” but my bag says “about 28 g”? The label reports protein per serving, not per 100 g. If you want the 100 g value, you need to scale it, which is exactly what this calculator does.
Are chips a good protein source? Most chips are low in protein compared with their calorie load. A standard 100 g portion of potato chips contains roughly 7 g protein and over 500 calories, while the same calories of chicken breast or Greek yogurt would deliver far more protein. Chips can still fit in a balanced diet, but they work best as a snack alongside a protein-rich dip.
Does the calculator work for baked chips? Yes. As long as you know the serving size in grams and protein per serving, the math is identical. Baked chips are often lower in fat but not necessarily higher in protein.
Why is 100 g used as the standard? Food scientists and nutrition databases use 100 g so that different foods can be compared on the same scale, regardless of portion size. If your snack is a small 28 g bag, don’t eat 100 g—use the per-100g number as a density guide, not a serving suggestion.
