The image above represents dry unit weight of soil. To calculate dry unit weight of soil, two essential parameters are needed and these parameters are **Unit weight of soil (Î³)Â **andÂ **Moisture content (w).**

The formula for calculating dry unit weight of soil:

Î³_{d}Â =Â ^{Î³}Â /Â _{1 + w}

Where:

Î³_{d}Â = Dry Unit Weight of Soil

Î³ = Unit Weight of Soil

w = Moisture Content

Let’s solve an example;

Find the dry unit weight of soil when the unit weight of soil is 12 and the moisture content is 6.

This implies that;

Î³ = Unit Weight of Soil = 12

w = Moisture Content = 6

Î³_{d}Â =Â ^{Î³}Â /Â _{1 + w}

That is, Î³_{d}Â =Â ^{12}Â /Â _{1 + 6}

Î³_{d}Â =Â ^{12}Â /Â _{7}

Î³_{d} = 1.71

Therefore, theÂ **dry unit weight of soilÂ **isÂ **1.71.**

**Calculating for the Unit Weight of Soil when the Dry Unit Weight of Soil and the Moisture Content are Given**

Î³ = Î³_{d} (1 + w)

Where;

Î³ = Unit Weight of Soil

Î³_{d}Â = Dry Unit Weight of Soil

w = Moisture Content

Let’s solve an example;

Find the unit weight of soil when the dry unit weight of soil is 22 and the moisture content is 12.

This implies that;

Î³_{d} = Dry Unit Weight of Soil = 22

w = Moisture Content = 12

Î³ = Î³_{d} (1 + w)

Then, Î³ = 22 (1 + 12)

Î³ = 22 (13)

Î³ = 286

Therefore, theÂ **unit weight of soilÂ **isÂ **286.**

**Calculating the Moisture Content when the Dry Unit Weight of Soil and the Unit Weight are Given**

w = ^{Î³} / _{Î³d} – 1

Where;

w = Moisture Content

Î³_{d}Â = Dry Unit Weight of Soil

Î³ = Unit Weight of Soil

Let’s solve an example;

Find the moisture content when the dry unit weight of soil is 6 and the unit weight of soil is 24.

This implies that;

Î³_{d} = Dry Unit Weight of Soil = 6

Î³ = Unit Weight of Soil = 24

w = ^{Î³} / _{Î³d} – 1

So, w = ^{24} / _{6} – 1

w = 4 – 1

w = 3

Therefore, theÂ **moisture contentÂ **isÂ **3.**
