Density Of Gold The Physics Factbook

Specific gravity of gold (then recorded as 19.2) was important to the gold miners of the mid-1800s for when they needed to determine whether they had gold or fools gold since they did not have any quality measuring devices. The high density of gold also allowed a common form of gold accumulation called panning.

How To Calculate The Specific Gravity Of A Substance Dummies

By Steven Holzner. In physics, a substances specific gravity is the ratio of that substances density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m 3, that ratio is easy to find. For example, the density of gold is 19,300 kg/m 3, so its specific gravity is the following

Calculating Density

Jun 19, 2020 Jun 19, 2020 However, specific gravity is a unitless number, and is the same in the metric system or any other measurement system. It is very useful when comparing the density of two objects. Since specific gravity is unitless, it doesnt matter whether the density was measured in g/cm 3 or in some other units (like lbs/ft 3).
