O.K. Bonehead(your choice of words)
Your only defense is if you are American
This is metric so make it a decimal
Not 100% sure of the problem you are having but
1/6ppm is not the end result
1 divided by 6 = .16666666ppm
Working the other way
.8 x 15 x 1ppm(max recommended) = ml
12 x 1 =12ml
or
.8 x 15 x .15ppm(min recommended) = ml
12 x .15 =ml
1.8ml
If NASA scientists are so bright why do they count backwards?
