Determine an M Weight

Given size (width) =
Given size (length) =
Basis weight =
Basic size (width) =
Basic size (length) =

M Weight =

Formula:

Given Size x Basis Weight	=	Rounded Ream Weight x 2	=	M Weight
Area of Basic Size

Example:

Calculate the M Weight of a 28x40 70# Opaque sheet.

(28 x 40) x 70	=	83 lbs. x 2	=	166 lbs.
25 x 38

Table 1: Rounding Rules
Sheet Size	Ream Weight
864 inches² or larger	Ream Weight calculated to the nearest pound (166 lbs.)
336 inches² to 864 inches²	Ream Weight calculated to the nearest ½ pound (166.5 lbs.)
Less than 336 inches²	Ream Weight calculated to nearest one hundredth of a pound (166.55 lbs.)
