The formula to calculate the Pg/Vg Ratio (PVR) is:
\[ PVR = \frac{Pg}{Vg} \]
Where:
The Pg/Vg Ratio is a measure used in various industries, including vaping and cosmetics, to describe the proportion of propylene glycol (Pg) to vegetable glycerine (Vg) in a mixture. This ratio affects the viscosity, flavor, and vapor production of the mixture.
Let's say the total propylene glycol (Pg) is 60, and the total vegetable glycerine (Vg) is 40. Using the formula:
\[ PVR = \frac{60}{40} = 1.5 \]
So, the Pg/Vg Ratio (PVR) is 1.5.
