How much does pencil weigh in ounces?
#2 wooden pencils vary by the type of wood used, from 6 to 10 grams each (0.2 to 0.3 ounces). I just individually weighed 8 unused old-fashioned wooden pencils. All were unsharpened and had unused erasers. They were all about 7½" long. Some were round, some were hexagonal. I used a digital scale accurate to 0.01 ounces. The weights ranged from 0.17 ounces to 0.22 ounces. Total weight of all eight pencils was 1.56 ounces, giving an average of 0.195 oz. Since all pencils had been stored in the same container, we can assume all had the same moisture content, so the small differences are explained by variances in the density of the type of wood used.
