Formula
[(Roll Diameter2) - (Core Diameter2)] × Roll Width × Factor = Roll Weight
Example
Find the weight of a roll of forms bond paper with a roll diameter of 40 inches, a core diameter of 3 inches, and a roll width of 17.5 inches.
[(40 × 40) - (3 × 3)] × 17.5 × .021 = 585 lbs.
Note: .021 is the appropriate factor for forms bond paper.
