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 

To calculate the batch weight, multiply the net mixer volume, density, and fill factor together.

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 =  ?
