Looking up the specifications of an oil online, the spec sheet indicates that the specific gravity of this oil is .93.
Does this mean that the oil weights .93 grams / 1 cubic centimeter of oil?
Thanks
Specific gravity has no units but the s.g. is the same as the density if the measurement is made against water with a density of 1.00 g/cc. Therefore, the oil you looked up has a mass of 0.93 g/cc when compared to water at a density of 1.00 g/cc. Thus it is lighter than water and will float on water.
No, the specific gravity of a substance does not directly indicate its weight in grams per cubic centimeter (g/cm³). Specific gravity is actually a dimensionless value that compares the density of a substance to the density of a reference substance. The reference substance is typically water, which has a specific gravity of 1.
To understand the weight of the oil, you would need to know its density in grams per cubic centimeter (g/cm³), as well as the volume of the oil in question. The weight of an object, such as oil, can be calculated using the formula:
Weight = Density x Volume
If you have the specific gravity of the oil, you can convert it to density by multiplying it by the density of the reference substance. In the case of water, the density is approximately 1 g/cm³.
For example, if the specific gravity of the oil is 0.93, the density can be calculated as follows:
Density = Specific Gravity x Density of Water
= 0.93 x 1 g/cm³
= 0.93 g/cm³
Once you have the density, you can multiply it by the volume of the oil in cubic centimeters to calculate the weight in grams.
It's important to note that specific gravity is not the same as density, and specific gravity alone does not provide the weight of a substance. You would need to convert the specific gravity to density and use the appropriate formula to calculate the weight.
