Enter the wet density (pcf) and the moisture content (pcf) into the Calculator. The calculator will evaluate the Field Density Test. 

Field Density Test Formula



  • FDT is the Field Density Test (pcf)
  • WD is the wet density (pcf)
  • MC is the moisture content (pcf)

To calculate the Field Density Test, subtract the moisture content from the wet density.

How to Calculate Field Density Test?

The following steps outline how to calculate the Field Density Test.

  1. First, determine the wet density (pcf). 
  2. Next, determine the moisture content (pcf). 
  3. Next, gather the formula from above = FDT = WD – MC.
  4. Finally, calculate the Field Density Test.
  5. 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.

wet density (pcf) = 1020

moisture content (pcf) = 102
