°API = [ 141.5 / (SG @ 60°F) ] - 131.5
SG= specific gravity (always taken at 60°F when calculating API)
Veq = 133000*(Condensate specific gr/Mol wt of condensate) in SCF/STB Where, Mol wt of condensate = 6084/(API-5.9)
The relevant Standards are API Specification 10A/ISO 10426-1 Specification for Cements and Materials for Well Cementing. API Classes have letter designations. Historically these have included A, B, C, D, E, F, G, H, J (there was never an "I" because that might be confused with ASTM Type I) Class J was dropped a number of years ago and E and F will be dropped in the next API/ISO document revision. G and H the more commonly used today. There are good books on the topic. The best is probably Nelson and Guillot, Well Cementing 2nd edition. Since I am not sure of the motivation for the question, I may not have met the questioner's needs.

Basra is both a state capital and a state of Iraq. The largest field in the state is the Rumaila field, a huge field as documented in the second reference. Not only is there variation of properties from field to field, but also well to well within the same field. Therefore, the oil is divided into Basra light, medium and heavy. A Basra blend is about 31.5 degrees API. The sulfur content is 1.95%. I couldn't find more specifications on the internet. Variations will also occur over time, as the less desirable heavy crude is usually produced later in the life of the fields. See related links.
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.

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.
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.
Specific gravity of crude oil is how light or heavy it is compared to water. If the API gravity is less than 10 it will float in water.
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
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
Depends on the API gravity. During the summer, diesel will weigh between 6.951 (API 38) and 7.076 (API 35) pounds per gallon. Last winter, the diesel weighed around 7.206 (API 32) pounds per gallon. You can do the math to convert this to metric.
Crude oil densities vary from Saudi Arabian fields, so a single specific gravity is not possible. However, for purposes of benchmarking crude, the Dubai crude is 31 degrees API (0.871).
The main difference between API 600 and API 503 valves is their port diameter. Also, the pressure testing between the two is different as well.
