Paper Weight Calculator
Standard methods to calculate paper and board characteristics require the use of the International System of Units (SI or SI metric units).
WEIGHT IN KG OF A GIVEN NUMBER OF SHEETS
Weight = L x Swd x Gsm x Ns / 1000
GRAMMAGE OF A SHEET OF PAPER IN G/M2
Grammage = W x 1000 / L x Swd x Ns
