Every 100 kcal of oil-roasted peanuts brings 4.7 g of protein. On that measure it ranks 45th of the 54 legumes in this database and 488th of all 796 foods on the site. Measured by weight instead, its 28 g per 100 g ranks 2nd in its group.
Around 19% of the calories in oil-roasted peanuts come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
By weight, fat outweighs protein in oil-roasted peanuts: 52.5 g of fat per 100 g against 28 g of protein, a ratio of 0.5 to 1.
Set against green peas, another legume entry in the database, a serving carries about 0.8 g less protein (green peas has 8.6 g per 1 cup cooked).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving quoted here is measured by weight at 28 g, and it covers about 16% of the 50 g FDA Daily Value for protein.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
How much protein is in 100 g of oil-roasted peanuts?
28 g. The 1 oz serving used on this page weighs 28 g and so carries 7.8 g.
How much protein do you get per 100 calories of oil-roasted peanuts?
4.7 g. That figure divides its 28 g of protein per 100 g by its 599 kcal per 100 g, so it does not depend on serving size.
Is the protein in oil-roasted peanuts complete?
No. On its own, the protein in oil-roasted peanuts is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of oil-roasted peanuts?
About 16%. One 1 oz serving has 7.8 g, and the FDA Daily Value for protein is 50 g.
