depend on the stone used for the gravel.
Density of loose soil is about 1200 kg/m3 1 cubic meter of soil may weigh more than this if compacted or moist.
10 lbs per sf.
The atmospheric pressure is roughly 1 bar, or 100,000 pascal. That means 100,000 newton per square meter (equivalent to the mass of about 10 tons). Actually, that's the approximate pressure at sea level; the pressure (force or weight per square meter) varies a lot depending on the altitude.
On average, 3mm toughened glass weighs approximately 7.5 kg per square 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
A 6mm toughened mirror typically weighs around 10-12 kilograms per square meter.
10mm toughened glass typically weighs around 25-30 kg per square meter. This weight may vary slightly depending on the specific manufacturing process and composition of the glass.
On average, 10mm thick toughened glass weighs approximately 7.5 kg per square meter. The weight may vary slightly depending on the specific type and manufacturing process of the glass.
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.

Well, when i was in the glass trade, glass was sold both millimetres with the ounces equivalent as follows:2mm = 16 ounces per sq ft4mm = 32 ounces per sq ft6mm = 48 ounces per sq ft1 sq metre = 10.7639104 sq foothope this is of help.
The weight of 1 square meter of 4mm thick glass is approximately 10.5 kilograms.
The weight of 12mm glass per square meter is approximately 28.8 kg/m². This may vary slightly depending on the specific type of glass and its composition.
