19 mm glass weight
19 mm glass weighs 47.5 kg per square metre, which is 4.41 kg or 9.73 lb per square foot. Float, toughened (tempered) and heat-strengthened glass weigh the same: the density is 2500 kg/m³ in every case.

Glass only, monolithic. The handling column is the calculator's guideline of 25 kg per person lifting with suction cups; the shape, the wind and the route can call for more people or a lifter.

How it is worked out
Weight = area × thickness × density. For one square metre of 19 mm glass: 1 m² × 0.019 m × 2500 kg/m³ = 47.5 kg. A square foot is 1/10.7639 of a square metre, so 47.5 ÷ 10.7639 = 4.41 kg, and × 2.20462 = 9.73 lb. The nearest US nominal thickness to 19 mm is 3/4".
