API gravity is a measure of how heavy or light a petroleum liquid is compared to water, with higher API gravity values indicating lighter oils. Specific gravity, on the other hand, is a measure of the density of a substance compared to the density of water. The two are related by the formula: API gravity = (141.5 / specific gravity) - 131.5.
API 24.8 corresponds to approximately 7.3 barrels per metric ton. This conversion factor helps to establish the volume of a given quantity of oil at that API gravity.
Specific gravity of a substance is defined as its density relative to the density of water. To convert the density of crude oil into specific gravity, you can divide the density of the crude oil by the density of water (1000 kg/m³ at 4°C). This will give you the specific gravity of the crude oil relative to water.
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.

The Formula for convert API gravity to pounds per gallon is: Pounds per Gallon = (141.5/(API Gavity+131.5))*8.3378 <--[which is weight of fresh water] API of 10 is same as weight of water. API >10 will float

Light liquids are substances that have a lower density compared to water, causing them to float on its surface. Examples include oils, alcohol, and certain organic solvents. These liquids are typically less dense due to their molecular structure or composition.

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 a measurement system used to determine the density of petroleum liquids like gasoline and diesel. It provides a standardized way to measure the specific gravity of these liquids, which is important for assessing their quality and purity. The API scale is commonly used in the oil and gas industry for fuel testing and analysis.
Iraq's fields produce from numerous formations, with varying crude densities. Many of these fields have large ranges, such as the Mauddud formation with a range of densities 12 to 38 degrees API. The two largest fields Kirkuk and Rumaila have average gravities of 32 to 33 degrees API. To convert from degrees API to specific gravity (SG), SG = 141.5/(131.5+API) See related links.
