Bulk Density Calculator

The loose bulk density of a powder is important to calculate when producing tablets. As a tablet has a fixed size you will need to know the loose bulk density of a powder to be able to determine if you need to add bulking agents or tamp the powder to be able to get you desired tablet weight.

To calculate the loose bulk density of the powder you will need a measuring jug/vessel/glassware that you know the exact size of and enough powder to fill it.

  1. Take your measuring jug and place it on the scales make sure to tare the scales so that they say zero.
  2. Fill the measuring jug to the top with powder. Make sure not to tap down or disturb the powder as you are pouring it into the jug.
  3. Record the weight of the powder in the jug.
  4. Divide the weight of the powder by the volume of the jug in mL.

Below is a video on how to calculate the loose bulk density of a powder:

Below we have built a calculator to help you do this.

You need to enter the size in mL
