Mix it up

Mixing differnt strengths


The easiest way is to mix eaquil amouts of both strengths
10mls of 1.8 mg + 10mls of1.2 mg = 3.0mg /20mls =1.5mg
so 1.8 + 1.2 is 3.0mg
but thats has doubled the volume so you half the strength.

1.8
1.8 +1.2=1.5
1.8 + .6= 1.2
1.2
1.8 + .3 = 1.0
1.2 + .6 = .9
1.2+.3 = 7.5
.6
.6 + .3 = 4.5
.3

you can also add zero strength if done in eaquil amounts
you half the strength

1.8 + 0 =.9
