Dilution calculation. Help!

[Xtro]

I seem to have a complete brain lock on this. It should be so simple but I'd appreciate your help. Here's the problem.

I've been trying out different strengths of e-liquid and bought some 18mg/ml strength Banana. Soon realised the nic strength was too much for my liking and chose to dilute it down with some Strawberry I have at 6mg/ml. I used equal quantities of each to keep it as simple as I thought possible. I mixed the two parts together and thought I'd get a liquid at 12mg/ml. After vaping this, it still hits too strong, so I'm doubting my numbers are correct.

Can someone tell me what the final strength is please? My apologies for hitting a blank on this. Thank you

You should be at 12 mg if you mixed 1/2 and 1/2

Just add up the total mgs that you have in the bottle and divide it by the total mls to get mg per ml

So, if you mixed 15 mls of 18 mg with 15 mls of 6 mg it would be
15X6 = 90
15x 18 = 270
total mgs in bottle = 360 divided by 30 mls liquid = 12 mg per ml

equal parts of the 18mg and the 6mg would be 12mg

Thank you guys. I thought I was correct but surprised at how strong it was as I've used 12mg before without a problem. Glad you cleared that up for me.
Perhaps it was the first time using an iClear30 and it felt stronger to me for some reason. Before that, it was Evods and a Mini Protank V2.
