What is the volume of an ounce of gold
++++
In order to calculate the material cost of gold plating a circuit, I need to know what is the volume of gold in one 24K troy ounce?

Gold has a density of 19.3g/cm3, so it can be worked out from that.

The Specific Gravity of Gold is 19.3. Therefore 19.3 grams occupy 1 cubic centimeter. 1 Troy ounce is 31.1 grams. So, to get the volume of 1 Troy Oz., we have 31.1/19.3 = 1.61 cubic centimeters.

hmm...
1.61*1.61*1.61=4.17 cubic centimeters.
you actually need to take the cubic root of 1.61.
roughly, 1.172 cubic centimeters.

Hi,
Everyone's numbers are correct but there has been a little pit of confusion about units. A small "dice cube" of gold, 1.172 cm long x 1.172 cm x 1.172 cm high will have a volume of 1.61 cubic centimeters and will weigh 1 Troy ounce.
