# Water Content

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

\(\large{ w = \frac{M_w}{M_s } }\) | |

\(\large{ w = \frac{W_w}{W_s } }\) | |

\(\large{ w = \frac{ S \; e }{ G_s } }\) |

### Where:

\(\large{ w }\) = water content (% moisture contemt) | \(\large{dimensionless}\) | |

\(\large{ S }\) = degree of saturation (expressed as %) | \(\large{dimensionless}\) | |

\(\large{ M_s} \) = mass of solid | \(\large{lbm}\) | \(\large{kg}\) |

\(\large{ M_w }\) = mass of water | \(\large{lbm}\) | \(\large{kg}\) |

\(\large{ G_s }\) = specific gravity of soil | \(\large{dimensionless}\) | |

\(\large{ e }\) = void ratio | \(\large{dimensionless}\) | |

\(\large{ W_s} \) = weight of solid | \(\large{lbf}\) | \(\large{N}\) |

\(\large{ W_w }\) = weight of water | \(\large{lbf}\) | \(\large{N}\) |
