specific gravity of gold

Specific Gravity of Gold Calculation Learn how to easily

Once you determine the specific gravity, it is important to note that tungsten gold bars are almost the same specific gravity as 24k gold bars. Tungsten’s specific gravity is 19.25 and 24k gold is 19.32. Given these two are so close together, if you are still second guessing and are buying large quantities of gold, you may want to consider the sigma metalytics precious metals tester which penetrates the item

Relative density Wikipedia

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" is often preferred in
