WebApr 2, 2024 · Specific gravity = Density of an object Density of water The units cancel out in the ratio. Therefore, the specific gravity is a unitless number. The density of water is 1.0 g/mL at room temperature, so the specific gravity is equal to the density of the object expressed without a unit.

The density of liquid hydrogen is only 70.85 g/L (at 20 K ), a relative density of just 0.07. Although the specific energy is more than twice that of other fuels, this gives it a remarkably low volumetric energy density, many fold lower.
