Density of Phosphoric Acid🪨 (H3PO4) {🪨 2022 update}

Definition

The density of phosphoric acid is the weight of phosphoric acid 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 phosphoric acid density in kg/m³ (SI unit), g/cm³, g/ml, kg/l, lb/ft³.

Density of Phosphoric Acid

85%

𝛒 = 1.685 g/cm³

𝛒 = 1685 kg/m³

𝛒 = 1.685 g/ml
𝛒 = 1685 g/L

𝛒 = 105.19 lb/ft³

75%

𝛒 = 1.63 g/cm³

𝛒 = 1630 kg/m³

𝛒 = 1.63 g/ml
𝛒 = 1630 g/L

𝛒 = 101.76 lb/ft³
