## Water density

Density of Water (H2O) is 1000 kg/m3 (Rounded value for water density, commonly used in simple calculations. ). *

Volumetric mass density of Water (water) in other popular units:

= 1 [kg/L] or [g/mL] or [g/cm3] or [t/m3]

= 0.578036672 [oz/cu in] (Avoirdupois ounce per cubic inch)

= 1.04317556 [oz/US fl oz] (Avoirdupois ounce per fluid ounce)

= 0.036127292 [lb/cu in] (Avoirdupois pound per cubic inch)

= 62.427961 [lb/cu ft] (pound per cubic foot)

= 1685.5549 [lb/cu yd] (pound per cubic yard)

= 8.34540445 [lb/US gal] (pound per US liquid gallon)

## Specific gravity (or relative density)

SGw4°C = 1.00002510063 (relative to 4°C water)

SGair20°C = 830.49580599618 (relative to 20°C air)
