15 mm glass weight
15 mm glass weighs 37.5 kg per square metre, which is 3.48 kg or 7.68 lb per square foot. Float, toughened (tempered) and heat-strengthened glass weigh the same: the density is 2500 kg/m³ in every case.
Weight of 15 mm glass by size

| 1 square metre | 37.5 | 82.7 | Two people, by the guideline |
| 2 × 3 ft (610 × 914 mm) | 20.9 | 46.1 | One person, by the 25 kg guideline |
| 4 × 8 ft (1219 × 2438 mm) | 111.5 | 245.8 | Mechanical lifter |
| Stock sheet 2440 × 1830 mm (8 × 6 ft) | 167.4 | 369.2 | Mechanical lifter |
| Door panel 900 × 2100 mm | 70.9 | 156.3 | Three or four people, or a lifter |

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 15 mm glass: 1 m² × 0.015 m × 2500 kg/m³ = 37.5 kg. A square foot is 1/10.7639 of a square metre, so 37.5 ÷ 10.7639 = 3.48 kg, and × 2.20462 = 7.68 lb. The nearest US nominal thickness to 15 mm is 5/8".

Questions people ask
- How much does 15mm glass weigh per square foot?
- 3.48 kg (7.68 lb) per square foot, or 37.5 kg per square metre, because glass has a density of 2500 kg/m³.

- A 900 × 2100 mm panel weighs 70.9 kg (156.3 lb). By the calculator's guideline: three or four people, or a lifter.
- Does 15 mm toughened glass weigh more than ordinary glass?
- No. Toughening changes the stresses in the glass, not its density: 15 mm toughened (tempered) glass weighs the same as float, 37.5 kg/m².
- What does a 15 mm sheet of 2440 × 1830 mm (8 × 6 ft) weigh?
