Every 100 kcal of dry roasted pecans brings 1.3 g of protein. On that measure it ranks 24th of the 31 nuts in this database and 743rd of all 796 foods on the site. Measured by weight instead, its 9.5 g per 100 g ranks 21st in its group.
Only about 5% of the calories in dry roasted pecans come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
By weight, fat outweighs protein in dry roasted pecans: 74.3 g of fat per 100 g against 9.5 g of protein, a ratio of 0.1 to 1.
Set against macadamia nuts, another nut entry in the database, a serving carries about 0.5 g more protein (macadamia nuts has 2.2 g per 1 oz).
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 5% 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 dry roasted pecans?
9.5 g. The 1 oz serving used on this page weighs 28 g and so carries 2.7 g.
How much protein do you get per 100 calories of dry roasted pecans?
1.3 g. That figure divides its 9.5 g of protein per 100 g by its 710 kcal per 100 g, so it does not depend on serving size.
Is the protein in dry roasted pecans complete?
No. On its own, the protein in dry roasted pecans 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 dry roasted pecans?
About 5%. One 1 oz serving has 2.7 g, and the FDA Daily Value for protein is 50 g.
