Water content, abbreviated as w, also called moisture content, a dimensionless number, is the ratio of weight of soil to the weight of water or the quantity of water contained in a material.

## water content formulas

$$\large{ w = \frac{W_w}{W_s } }$$
Symbol English Metric
$$\large{ w }$$ = water content (% moisture contemt) $$\large{dimensionless}$$
$$\large{ W_s}$$ = weight of solid $$\large{lbf}$$ $$\large{N}$$
$$\large{ W_w }$$ = weight of water $$\large{lbf}$$ $$\large{N}$$
