LB per FT² = BW
                  3000

$/FT² = LB. per FT² X $ per LB

$ per MSF = $/Ton X BW
                            6000

$ per LB. = $/CWT
                   100

$ per Ton = 6000 X BW + $ per MSF X 6000

M Weight = L X W X BW
                       432

$ per Sheet = M Weight X $ per LB.
                       1000

Number of Sheets = Total Weight
                              LB. per sheet

Order Weight = LB/Sheet X Number of Sheets

Linear Feet in Roll = 41.67 X Net Weight (lb.) X 864
                                       Roll Width X BW

Roll Weight = OD² - ID² Roll Width X BW X .00182
Caliper [.020" = 20]

Roll Weight from Lineal Feet = Roll Width X BW X Lineal Ft.
                                                          36,002

Price per Linear Foot = Weight (lb.) X $/cwt.
                                         Linear Feet

Notes:
· BW = Basis Weight
· All formulas with basis weights assume a 36 X 24" cover basis (3000 FT²)
     · (36*24)/144*500 [i.e., the weight per 500 sheets or ream]
· MSF = 1000 Square Feet
