## Hydrogen density

Density of Hydrogen (H) is 0.08988 kg/m3 . *

Volumetric mass density of Hydrogen (chemical elements) in other popular units:

= 8.988E-5 [kg/L] or [g/mL] or [g/cm3] or [t/m3]

= 5.195393607936E-5 [oz/cu in] (Avoirdupois ounce per cubic inch)

= 9.37606193328E-5 [oz/US fl oz] (Avoirdupois ounce per fluid ounce)

= 3.24712100496E-6 [lb/cu in] (Avoirdupois pound per cubic inch)

= 0.00561102513468 [lb/cu ft] (pound per cubic foot)

= 0.151497674412 [lb/cu yd] (pound per cubic yard)

= 0.000750084951966 [lb/US gal] (pound per US liquid gallon)

## Specific gravity (or relative density)

SGw4°C = 8.9882256044627E-5 (relative to 4°C water)

SGair20°C = 0.074644963042937 (relative to 20°C air)
