The **Dry Unit Weight** calculator computes the Dry Unit Weight (aka bulk density) based on the oven dry mass and total volume of a sample.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**W**) Oven-dry mass of the sample_{S} - (
**V**) Total volume of the sample, pore volume + solid volume_{tot }

**Dry Unit Weight (γ _{D}):** The calculator returns bulk density in grams per cubic centimeter. However, this can be automatically converted to compatible units via the pull-down menu.

The Dry Unit Weight equation is used to determine a soil- sample's mass per unit volume by measuring the soil's wetness, volumetric water content, and porosity. It is also known as bulk density.

The formula for the Dry Unit Weight (bulk density) is:

γ_{D} = W_{S} / V_{tot}

where:

- γ
_{D}is the Dry Unit Weight (bulk density) - W
_{S}is the oven dry mass of the sample - V
_{tot }is the total volume of the sample, pore volume + solid volume
