25 mm glass weight
25 mm glass weighs 62.5 kg per square metre, which is 5.81 kg or 12.80 lb per square foot. Float, toughened (tempered) and heat-strengthened glass weigh the same: the density is 2500 kg/m³ in every case.

|---|---|---|---|
| 1 square foot (12 × 12 in) | 5.8 | 12.8 | One person, by the 25 kg guideline |
| 1 square metre | 62.5 | 137.8 | Three or four people, or a lifter |
| 2 × 3 ft (610 × 914 mm) | 34.8 | 76.8 | Two people, by the guideline |
| 4 × 8 ft (1219 × 2438 mm) | 185.8 | 409.6 | Mechanical 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 25 mm glass: 1 m² × 0.025 m × 2500 kg/m³ = 62.5 kg. A square foot is 1/10.7639 of a square metre, so 62.5 ÷ 10.7639 = 5.81 kg, and × 2.20462 = 12.80 lb. The nearest US nominal thickness to 25 mm is 1".

Questions people ask
- How much does 25mm glass weigh per square foot?
- 5.81 kg (12.80 lb) per square foot, or 62.5 kg per square metre, because glass has a density of 2500 kg/m³.
- How heavy is a 25 mm glass door?
- A 900 × 2100 mm panel weighs 118.1 kg (260.4 lb). By the calculator's guideline: mechanical lifter.
- Does 25 mm toughened glass weigh more than ordinary glass?
- No. Toughening changes the stresses in the glass, not its density: 25 mm toughened (tempered) glass weighs the same as float, 62.5 kg/m².
- What does a 25 mm sheet of 2440 × 1830 mm (8 × 6 ft) weigh?
- 279.1 kg (615.3 lb).
