2020-12-18 · By Steven Holzner . In physics, a substance’s specific gravity is the ratio of that substance’s 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:

2020-6-21 · The specific gravity will vary depending on the temperature inside the batteries. The manual for your batteries will tell you what correction to apply. For example, this is what the Surrette/Rolls manual says for temperatures in the range 0 to 130°F or -17.8 to 54.4°C. Use the equations below or for temperatures below 70°F (21°C) subtract 0

More ### The Hydrometer Test for Specific Gravity

The hydrometer, invented in the early eighteenth century, is a simple floating device calibrated to measures the specific gravity or density of a liquid. It is readily available at your local home brew shop, is inexpensive and has several important vinegar making uses. If you are making apple cider vinegar from apple juice, this test unit can be used to determine the amount of sugar in the
