Displacement and extra volume
mL/g

Volume one gram of powder occupies. 0.75 is the usual assumption if you have not measured a density.

%

Scales every ingredient and keeps the concentration. Use it for what a filter and a transfer will hold back.

Oil = finished volume − powder × displacement − each solvent.

Arithmetic for weighing an oil solution. It is not a dose, a sterility method, or medical advice. Many of these substances are prescription-only or controlled, and preparing them can be unlawful where you live. Molecular weights are anhydrous formula weights. Liquid grams use typical densities, not an assay of your bottle.
