To convert API gravity to density in g/cm^3, you can use the formula: Density = 141.5 / (API gravity + 131.5). This formula is derived from the relationship between API gravity and density in the petroleum industry.
API gravity is inversally proportional to the specific gravity. so if the value of spcific gravity for some material is higher , it means that the API gravity of the same material will be lower.
The same way you convert any density to specific gravity. Just divide the density of the substance (crude oil in this case) by the density of the reference substance (usually water, for liquids).

The weight of a barrel of oil will depend on its density. A barrel contains 42 gallons and density is typically measured in units of API gravity. Units can be a bit confusing in this case. We need to convert from API density to pounds per gallon. Crude oil can typically vary from 15 to 45 deg API although I have worked with oils as low as 8 and as high as 50. Let us consider oil gravity of 30 deg API, as all other densities are calculated in the same way. Specific Gravity = 141.5/(131.5 + 30) = 0.876 The specific gravity is the density of the oil relative to water. Now, to convert this to pounds per gallon, we must multiply the answer by 8.34 (density of water is 8.33 pounds per gallon): 8.34 x 0.876 = 7.30 pounds/gallon. Since there are 42 gallons in a barrel, we must multiply this answer by 42: 42 x 7.30 = 307 pounds. To summarize, a) convert API to specific density b) convert specific density to pounds per gallon and c) multiply gallons in one barrel by the pounds per gallon.
In the API gravity formula, 141.5 is a constant used to standardize the API gravity scale. It represents the specific gravity of water at 60°F. 131.5 is the specific gravity of the liquid being measured. By subtracting 131.5 from 141.5 and dividing the result by 0.1, you can calculate the API gravity of the liquid.
Well, darling, API gravity is a measure of how heavy or light a petroleum liquid is compared to water. To convert API gravity to pounds per gallon, you'll need to use a specific formula that takes into account the density of water and some other fancy factors. So, grab your calculator and get ready to crunch some numbers if you want to make that conversion happen.

By using API gravity value of a liquid we can check that how a liquid is lighter or haavior one.First we should know about API gravity.The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a liquid is compared to water. If its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. API gravity is thus an inverse measure of the relative density of a petroleum liquid and the density of water, but it is used to compare the relative densities of petroleum liquids. For example, if one petroleum liquid floats on another and is therefore less dense, it has a greater API gravity. Although mathematically, API gravity has no units (see the formula below), it is nevertheless referred to as being in "degrees". API gravity is graduated in degrees on a hydrometer instrument. The API scale was designed so that most values would fall between 10 and 70 API gravity degrees.M.Hassan Haq NawazB.sc. Chemical Engg,University Of Gujrat,Pakistan
It is spelled "density" and specific gravity is a measure of density and so does not need to be converted.

The American Petroleum Institute (API) scale on hydrometers is an arbitrary scale based on Relative Density (Specific Gravity) where - API = (141.5 divided by the Relative Density at 60oF) - 131.5
In the API gravity formula, 141.5 is a constant used to standardize the API gravity scale. It represents the specific gravity of water at 60°F. 131.5 is the specific gravity of the liquid being measured. By subtracting 131.5 from 141.5 and dividing the result by 0.1, you can calculate the API gravity of the liquid.
