Capsule Fill Weight and Diluent
Diluent and fill weight per capsule and per batch, from measured fill weights or capsule volume and tapped densities.
Open the tool → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Method: measured fill weights of each powder alone (weights)
- From measured fill weights of each powder alone
- Number of capsules
- 30
- Active per capsule
- 100 mg
- Weights method: active alone that fills one capsule
- 400 mg
- Weights method: diluent alone that fills one capsule
- 300 mg
Result: 225 mg of diluent with 100 mg of active per capsule; for 30 capsules, 3 g of active and 6.75 g of diluent.
The tool opens with these values already filled in. Replace them with your own.

- Number of capsules
- Extra capsules to allow for loss (optional)
- Active per capsule
- Weights method: active alone that fills one capsule

- Densities method: tapped density of the diluent
How this is calculated

Arithmetic identity (the capsule holds a fixed volume): the diluent fills the fraction of the capsule the active leaves. Fill weights, the capsule volume and tapped densities are the reader's own measurements or the capsule maker's figures.
