Density of Tap Water {🪨 2022 update}

Definition

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

Density of Tap Water

At 25 °C (77 °F or room temperature) and 1 atm:

𝛒 = 0.99713 g/cm³

𝛒 = 997.13 kg/m³

𝛒 = 0.99713 g/ml
𝛒 = 997.13 g/L

𝛒 = 0.99713 kg/l
𝛒 = 0.99713 kg/L

𝛒 = 62.2488 lb/ft³
𝛒 = 8.32145 lb/gal
