Take a paper of standard size. Measure its mass in gram using an electronic balance. Find its dimensions (length and breadth) in meter. Find the area in meter2. Get the gsm by dividing the mass in gram by area in meter2.
Example: If the mass of a 42cmx33.5cm paper is 8.15gram then its gsm is 58 .
(8.15/.42/.335 = 58)
You will get more accurate results by using multiple sheets of paper. I usually use at least 10 sheets of paper, then you can either find the total area of the 10 sheets (multiply area of 1 sheet by 10), or divide the mass that you measured by 10, before doing the gsm calculation.

CoachTo calculate the grammage of a paper in grams per square meter (GSM), you need to weigh a standard-sized sheet of the paper in grams and then measure the area of the sheet in square meters. Divide the weight of the paper by the area to get the GSM value, which indicates the weight of the paper in grams per square meter.

How do you convert gsm of paper into mm?
To convert grammage (gsm) of paper into thickness (mm), you must know the density of the paper. Paper density varies depending on the type of paper. However, as a general approximation, you can convert by using the formula: thickness (mm) = gsm / density (g/cm³).
How do you calculate gsm of polyethylene?
To calculate the GSM (grams per square meter) of polyethylene, you need to know the weight in grams of a known area of the material. Measure a specific area of the polyethylene sample, weigh it in grams, and then divide the weight by the area measured to determine the GSM. The formula for calculating GSM is GSM = (Weight in grams / Area in square meters).
What is the weight of a ream of copy paper?
For 80 gsm paper, it is approx 2.495 kilograms.
How much does 1 ream of paper weigh?
A ream of paper is 20 quires of paper.A quire is defined in different ways.As a number it is currently 25 sheets of paper, but formerly it was 24 sheets.So, if we assume that a quire is 25, and a ream is 20 quires, then a ream is 20 x 25, which is 500 sheets.All you have to do now is to find the weight of 1 sheet of paper and multiply it by 500!Paper is often sold in different weights. The 'weight' indicates its thickness.A typical 'copy' paper A4 size, for use on a home PC printer, weighs about 80 grams per square meter (gsm).A Premier Photo paper might weigh 250 gsm.So the weight of a ream of paper depends on1. the 'gsm' weight/quality of the paper2. the size of each sheet in the reamA ream (500 sheets) of A4 paper, 80 gsm, weighs about 2.4 Kg But a ream of A3 size paper, a sheet of which is twice the sizeof an A4 sheet, weighs about 4.8 Kg
What is the thickness of newsprint?
Newsprint paper typically ranges in thickness from 40 to 52 grams per square meter (gsm), which translates to about 0.043 to 0.055 millimeters in thickness.
