What density does the calculator use for each glass type?

Float glass uses 2,500 kg/m³, tempered glass 2,500 kg/m³, laminated glass 2,700 kg/m³ (accounts for the PVB interlayer), frosted glass 2,500 kg/m³, and wired glass 2,600 kg/m³.

Can I use inches or feet instead of millimeters?

This calculator uses millimeters (mm) for all dimensions. Convert inches to mm by multiplying by 25.4, or feet by multiplying by 304.8.

Does laminated glass weigh more than standard float glass?

Yes. Laminated glass consists of two or more glass layers bonded with a PVB or resin interlayer, which adds to the overall weight. Its effective density is approximately 2,700 kg/m³.

Is tempered glass heavier than regular float glass?

No. Tempering is a heat treatment process that changes the mechanical properties but not the density. Tempered glass has the same density as float glass (~2,500 kg/m³).

How accurate is this calculator?

Results are accurate for standard flat glass using nominal density values. Minor variations may occur due to manufacturing tolerances or non-standard compositions. Always verify critical load calculations with a structural engineer.
