Enter the total weight of dry soil (g), the total weight of moisture (g), and the total volume of wet soil (cm^3) into the Saturated Unit Weight of Soil Calculator. The calculator will evaluate the Saturated Unit Weight of Soil. 

Saturated Unit Weight of Soil Formula

The following formula is used to calculate the Saturated Unit Weight of Soil. 

Y = (WDS + WM) / V

Variables:

  • Y is the Saturated Unit Weight of Soil (g/cm^3)
  • WDS is the total weight of dry soil (g) 
  • WM is the total weight of moisture (g) 
  • V is the total volume of wet soil (cm^3) 

How to Calculate Saturated Unit Weight of Soil?

The following steps outline how to calculate the Saturated Unit Weight of Soil.


  1. First, determine the total weight of dry soil (g).
  2. Next, determine the total weight of moisture (g). 
  3. Next, determine the total volume of wet soil (cm^3). 
  4. Next, gather the formula from above = Y = (WDS + WM) / V.
  5. Finally, calculate the Saturated Unit Weight of Soil.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

total weight of dry soil (g) = 30

total weight of moisture (g) = 20

total volume of wet soil (cm^3) = 10

Y = (WDS + WM) / V =  ?
