There are 16 oz in a lb.
20 lb batch x 16 oz = 320 oz.
So for Tin 320 x .02 = 6.4 oz
for Antimony 320 x .06 = 19.4 oz = 1 lb 3.4 oz
for Lead 320 x .92 = 294.4 oz = 18 lb 4 oz.
To be exact. Above posted numbers in another post are close enough to get that mix but I am anal and thought someone may enjoy the math to get it to a gnats a$$.
