Density of Fiberglass 🪨

Definition

The density of fiberglass is the weight of fiberglass per its volume.

Formula

ρ = m / V

• ρ:  Density
• m: mass
• V: Volume

Density vs Specific Weight vs Specific Gravity

I would like to point out that there are conceptual differences between density, specific weight and specific gravity. Follow the link if you want to learn more about these differences.

With that said, this page will provide you the fiberglass density in kg/m³ (SI unit), g/cm³, g/ml, kg/l, lb/ft³.

Density of Fiberglass (Boron / E-Glass)

𝛒 = 2.6 g/cm³

𝛒 = 2600 kg/m³

𝛒 = 2.6 g/ml
𝛒 = 2600 g/L

𝛒 = 162.31 lb/ft³
