MSI/MSF
Estimate the thousands of square inches (MSI) and square feet (MSF) in a roll of paper of a given grade and basis weight.
Weight of Roll ÷ (Basis Weight ÷ [Area of Basic Size]) × 2 = MSI ÷ 144 = MSF
The MSI and MSF for a 900-pound roll of 80# book paper is 900 ÷ (80 ÷ [25×38]) × 2 = 5,344 MSI ÷ 144 = 37.111 MSF
