Calculation & assumptions
The suggestion favors a simple 1, 2, or 5 × power-of-ten amount per unit, then the largest final volume that fits. It does not choose a dose or a biologically suitable concentration.
The water estimate applies only to dry powder and assumes negligible powder displacement. Final solution volume, specified diluent, solubility, stability, sterility, cartridge compatibility, and working fill limits must be established separately. No allowance is made for priming or transfer losses.

Drops, sprays and other pen clicks need their own verified volume per increment. They have no universal conversion.
3 mL is cartridge capacity. It does not mean you must prepare or load 3 mL. The original vial and the pen cartridge are different containers. This reference compares measurement scales; it does not establish product or route compatibility.
