Enter the net mixer volume (m^3), the density of mixed batch (kg/m^3), and the fill factor into the Batch Weight Calculator. The calculator will evaluate the Batch Weight. 

Batch Weight Formula

The following formula is used to calculate the Batch Weight. 

BW = NMV * SG * FF


  • BW is the Batch Weight (kg)
  • NMV is the net mixer volume (m^3) 
  • SG is the density of mixed batch (kg/m^3) 
  • FF is the fill factor 

How to Calculate Batch Weight?

The following steps outline how to calculate the Batch Weight.

  1. First, determine the net mixer volume (m^3).
  2. Next, determine the density of mixed batch (kg/m^3). 
  3. Next, determine the fill factor. 
  4. Next, gather the formula from above = BW = NMV * SG * FF.
  5. Finally, calculate the Batch Weight.
  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.

net mixer volume (m^3) = 30

density of mixed batch (kg/m^3) = 5000

fill factor = .85

BW = NMV * SG * FF =  ?
