Frying removes the potato's water and leaves concentrated starch and oil: 532 kcal per 100 g. On the energy-density scale, 532 kcal per 100 g puts potato chips at the very high end. Fiber is the standout at 3.1 g per 100 g, which slows a portion down more than the calorie count suggests.
A typical serving (1 oz, about 15 chips, 28 g) has about 151 calories, and 100 g has 532 kcal. Calories scale with weight, so double the portion means double the number.
There are 6.4 g of protein in 100 g of potato chips, which works out to about 1.8 g per serving (1 oz). Treat it as an energy source rather than a protein source.
Yes, in the plain arithmetic sense: 34 g of fat per 100 g supplies about 58% of the calories. Whether that fits your day depends on your totals, not on the food alone.
Every value on this page comes from USDA FoodData Central, entry 169677 (SR Legacy). Serving figures are converted from the per-100-g data, so rounding can shift a total by a calorie or two.
