Use the calculator below if you have imported a Nicotine Base and want to know how much of it to add to your nicotine free e-liquid bottles to make a particular strength. Once all the fields are added the value will be automatically calculated below.

AddMilliliters to your bottle. Also remember to remove the same amount you are adding from your nicotine free e-liquid bottle before you add the nicotine base so that the total end volume of your bottle is as you stated above (or so your bottle is full after adding the base).
