e.g. 100 mg/mL freebase, 200 mg/mL salt concentrate.
Most freebase 100 mg/mL is 100% PG.
Common: 30/70 PG/VG (sub-ohm) or 50/50 (MTL).
Most concentrates are 100% PG.

How the math works
Nic base mL = (target mg/mL × total mL) ÷ base mg/mL. Flavour mL = total × flavour %. The remaining volume is filled with PG and VG so the whole mix hits your target PG/VG ratio — accounting for the PG carried in by the nic base and flavour.
Mass uses standard densities: PG = 1.036 g/mL, VG = 1.261 g/mL, nicotine ≈ 1.01 g/mL. If the calculator can't reach your target PG (e.g. you ask for 20% PG but your base + flavour already supply 25%), it will warn you and report the achievable ratio.
