6mm glass weighs 1.5Og/cm2. therefore 15Kg / m2

A4 paper 210mm by 297mm in size, which equals 62370 square millimeters. 150 GSM is 150 grams per square meter. 1 meter is 1000 millimeters, so 1 square meter is 1000x1000=1000000 square millimeters. You can fit 1000000/62370 A4 pages into 1sq meter, which is 16.0333493666827 pages. 150grams divided by 16.0333493666827 is 9.3555. So - a 150GSM page of A4 paper weighs 9.3555 grams.
barley in cubic meter
It depends on the size. If each sheet is 1/500 of a square meter large then the weight would be 130 grams. 130 gsm means 130 g/square meter. Thus, to find the weight, find the area of each sheet of paper in square meters, multiply it by the total number of pages (finding total square meterage) and then multiply it by 130.
Dry gravel with a size ranging from one quarter inch to two inches will weigh about 1,682 kilograms per cubic meter.

It depends on the glass type, but for general purposes it is about 19.8 kilograms per square meter
6mm glass weighs 16 kg/m2 or 3.27 lbs per square foot

25 kg/m2 is a density of a toughened glass with 10 mm thick. If you want convert that measure into kN, then multiply by the factor "g" that is gravity (9.81 m/s2) and you get 25 x 9.81 = 245.25 kN/m2.
50kg
The answer depends on the material and quality of the carpet.
You cannot weigh an area. Just as you cannot weigh a distance. (How much does one centimeter weigh?)
560 kilograms
GSM = grams per square meter Cut a 1 meter by 1 meter of fabric and weigh it in grams or weigh the fabric in grams (G) and measure the length in meters (L) and width in meters (W) and calculate: G/LW = grams per square meter = GSM
depend on the stone used for the gravel.
