Price/ linear ft

\$/lb / yield (sq ft/lb) x width (inches) x 12 = price/linear ft.

Price/msi

\$/lb / yield (sq ft/lb) x 1000 = \$ per msi

Price/roll

\$/lb / yield (sq ft/lb) x width (inches) x length (feet) x 12 = \$/roll

Length of roll from roll weight

lbs x yield (sq ft/lb) / width (inches) / 12 = linear feet

Length of roll from roll weight

lbs x yield (sq in/lb) / width (inches) = linear feet

Square inches / roll

width (inches) x length (feet) x 12 = sq inches

MSI / roll

width (inches) x length (feet) x 12 / 1000 = MSI

Lbs / roll

width (inches) x length (feet) x 12 / yield (sq inches) = lbs/roll
