The depth to which the hydrometer sinks is inversely proportional to the liquid’s specific gravity.
Specific gravity or density can measure the relationship between volume and weight.
The specific gravity is related with the ‘degree API,’ a measurement of the oil’s inherent power (regular, super, etc.).
The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.
Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).
Specific gravity and compressibility are highly connected and can be obtained one from the other.
Oil Industry: Crude oil and its refined products are normally measured either by volume in gallons and US barrels or by weight in tons.
One can gain a good idea of the shell’s state by measuring the whole egg’s specific gravity.
Soil’s Compressive strength: Engineers need to know a soil’s compressive strength to choose a construction method (among other things).
Eggshell thickness: Eggshell thickness is an important factor in the poultry industry.
