Looking for the formula or calculator to increase the nic level in E juice.
Example:

1. 30ml of premixed juice at 1.2% want to increase to 2.4% 70/30 pg/vg
2. 10ml of 0 nic premixed juice and want to make it 1.5 %

Have 10% pg nic.

The calculations are pretty easy if you us mg/ml instead of percentages. Most folks seem to have issues with percentages in math. I don't, but I've seen it as an issue on this sub a few times.

So if you have 30ml of 12mg/ml (1.2%) and want to make it 24mg/ml (2.4%) you would need to add 4.7ml of 100mg/ml (10%).
Check with 4.7ml * 100mg/ml = 470mg and 30ml * 12mg/ml = 360mg so 470mg + 360mg = 830mg in 34.7ml or 830mg / 34.7ml = 23.9mg/ml. Flavor will be that diluted too.

Add 1.8ml of 100mg/ml for 180mg with the 10ml of 0nic and you have 180mg / 11.8ml = 15.3mg/ml.
