Question:
I am making a mold for my decoy anchors. I need
10 - 12 lead ounce weights. How would I determine the liquid measurement for that weight? For example if I melted down 10 ounces of lead how many cups would that be or quarter cups etc?
I would like the formula if I could and good instructions on how to use the formula.
tks
very respectfully,
Jeff
Hi Jeff,
I looked up the specific gravity of lead and some conversion factors, and this is what I got.
lead weighs 11,340 kilograms/cubic meter
one cup is 0.0002365882 cubic meters
one ounce(weight) is 0.02834952 kilograms
one cup is 8 fluid ounces
Thus my calculation is
11340 ^{kg}/_{cu m} 0.0002366 ^{cu m}/_{cup} ^{1}/_{0.02835} ^{oz}/_{kg} ^{1}/_{8} ^{cups}/_{fluid oz}
= 11.82 ^{ounces}/_{fluid ounce
}
or
^{1}/_{11.82} = 0.085 ^{fluid ounces}/_{ounce}
So, in particular, if you melt down 10 ounces of lead you will have 0.85 fluid ounces.
