I am trying to figure out how much my molds hold so when my mold max arrives I can get to pouring. I have completed the build of my masters and measured out the Fluid ounces using sugar. My largest mold is 42floz so I will use that number.

I found that 1floz of water weighs 1.043oz resulting in the 42floz of water weighing 43.806oz. Since water has a specific gravity of 1 and Mold max has a Specific Gravity of 1.18 am I correct in saying 43.806 x 1.18 = 51.691oz of mold max will fill my mold?

This has 2floz added in case I am a bit off and to account for what sticks to the bowl but I like to keep waste to a minimum.

The Mold Max shipped today so I hope to have it at the beginning of next week if not sooner.

1 fluid ounce weighs 1 ounce, that's what a specific gravity of 1 means. So if you're weighing it to determine how much you need, you'll need 42 * 1.18 ounces = 49.52 ounces. But if you're "finding" that 1 ounce of water weighs 1.043 ounces, that's a measure of how far off your scale is and so you can use that as a correction and your number would be correct.

I found the 1.043 in a couple of different spots online.
 
It can get confusing because a fluid ounce is not a measure of weight.
(yeah, go figure.. it has the word 'ounce' in it, right?)
A fluid ounce is a measure of volume.. as compared to a dry ounce, which
is a measure of weight.

But in any case.. you'll need to either measure or calculate some other
way because your measurement with sugar included lots of air space.
And while the water will fill that same space, the sugar will settle as
it is moved, changing your volumetric reading.

Best bet is to measure the mold space in cubic inches. Then measure
your master in cubic inches and subtract that from your mold space.
That will give you the volume you need, which you can convert on the
page Curly mentioned. add another ounce or two for your mixing bowl
and spatula.. you'll never get it all out of the bowl!

Thanks Charlie, great info.
 
Skip the "ounces" altogether. It is archaic and confusing. Especially in an international setting (like this).:eek: "one ounce" has way to many definitions. is it weight, volume or what? is it avoirdupois? Troy, Imperial, Us ?

Use CC. Everybody knows what that means!
