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

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.
