How to determine ream weights
To determine ream weight (500 sheets) of any given size sheet, multiply the square inches in the given size by the given basis weight; divide the result by the square inch area of the basic size.

sheet size x basis weight / area of basic size = ream weight

Example: Find the ream weight of a sheet of 70lb. text paper.

23 x 35 x 70 / 25 x 38 = 56,350/950 = 59.32 lb. ream weight

How to determine M weights
M weight is the weight of 1,000 sheets. The M weight can be obtained by multiplying the ream weight by 2.

ream weight x 2 = M weight

Price per thousand sheets
cwt. price x M weight / 100 = price per 1,000 sheets
