20 Drops Isn't a ML!!

[oldbikeguy]

I'm kind of new to DIY but heres what I've found so far#1 I started a cookbook in it I keep a list of all the flavors I buy, the first time I use one I check drops/ml and write it next to that flavor so far most have come out 46/47 drops per ml thats with the same brand 1/ml pipettes I bought 50 of them and clean and reuse them.#2 for the other stuff I use 5/ml pipettes pg,vg, nic juice and also ckeck them and write it down, when I do a mix I just look them up in my cookbook and change the number in the drops per ml box for each thing I add, the thing I like about this method is with a little math I can deal with numbers like 1.67ml quick and easy.

Nope, drops ain't always drops... The number per ml is going to vary from drip tip to drip tip and from liquid to liquid depending on the viscosity of the liquid in question... Much better to use a metered syringe and go with the real ml value -- assuming, that is, that you've a quality syringe that's accurately metered...
