$\omega = \dfrac{Mass of Water}{Mass of Solids} = \dfrac{M_w}{M_s}$

Expressed in the %

The water content of the fine grained soils such as slit and clays is generally more than that of the coarse grained soils such as gravels and sand.

The water content of some fine grained soils may be even more than 100%, which indicates that more than 50% of the total mass of water.
