Enter the total propylene glycol and the total vegetable glycerine into the Calculator. The calculator will evaluate the Pg/Vg Ratio. 

Pg/Vg Ratio Formula

PVR = Pg/ Vg 


  • PVR is the Pg/Vg Ratio ()
  • Pg is the total propylene glycol
  • Vg is the total vegetable glycerine

To calculate Pg/Vg Ratio, divide the total propylene glycol by the total vegetable glycerine.

How to Calculate Pg/Vg Ratio?

The following steps outline how to calculate the Pg/Vg Ratio.

  1. First, determine the total propylene glycol. 
  2. Next, determine the total vegetable glycerine. 
  3. Next, gather the formula from above = PVR = Pg/ Vg
  4. Finally, calculate the Pg/Vg Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total propylene glycol = 70

total vegetable glycerine = 100
