It is common to use the density of water at 4 oC (39 oF) as reference - at this point the density of water is at the highest. Specific gravities - SG - for common solids and metals can be found in the table below:
Specific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. Physicists use 39.2 F (4 C) as the standard, but engineers ordinarily use 60 F. In the International System of Units (SI Units), the density of water is 1.00 g/cm 3 at the standard temperature.
The specific gravity of all other materials are compared to water as a fraction heavier or lighter density. For example, beryllium has a specific gravity (sg) of 1.84
3 Οκτ 2013 · Pure water at 4°C (the maximum density) was chosen as the accepted standard for specific gravity and given the value of 1. Some other standards set pure water at 60°F as sg = 1 so it is more correct to state the base used.
31 Οκτ 2023 · To find the specific gravity of a metal, you need to divide its density by the density of water at 4°C (approximately 1 g/cm³). How to calculate specific gravity? Specific gravity is calculated by dividing the density of a substance by the density of water at 4°C (approximately 1 g/cm³). Which metal has the highest specific gravity?
Specific gravity is the density of a substance divided by the density of water. The density units cancel, leaving specific gravity a unitless number. Since we often assume the density of pure water to be 1.0 g/mL, the specific gravity usually agrees closely with density. Temperature changes affect the density of
12 Αυγ 2011 · Pure water at 4°C (the maximum density) was chosen as the accepted standard for specific gravity and given the value of 1. Some other standards set pure water at 60°F as sg = 1 so it is more correct to state the base used.
