Vaping & E-Liquid
Nicotine strength and PG/VG ratio calculators for DIY vapers.
E-Liquid Nicotine Mixing Calculator
Mix DIY e-liquid: nicotine base, PG, VG and flavour for any target strength and PG/VG ratio.
PG/VG Ratio Calculator (Max VG)
Calculate the achievable PG/VG ratio of your DIY e-liquid given nicotine base and flavour PG/VG content.
What these tools are for
DIY e-liquid mixing is dilution arithmetic with a safety consequence, which is why the numbers are worth checking rather than estimating. The target strength, the strength of your nicotine base and the final volume together fix how much base goes in, and everything else is flavouring and the PG/VG balance.
PG and VG behave differently enough that the ratio is a real choice rather than a preference: VG is thicker and produces more vapour but wicks slowly and can starve a tight coil, while PG carries flavour and throat hit but is a more common irritant. Higher-VG mixes need larger wicking channels to work properly.
Nicotine is a toxin and concentrated base is hazardous to handle. These calculators do the arithmetic; they do not substitute for handling precautions, accurate scales or the supplier’s own stated concentration.
