With the formula presented in the previous section, the API gravity can be readily calculated. When converting oil density to specific gravity using the above definition, it is important to use the correct density of water, according to the standard conditions used when the measurement was made.
Use h for "per hour", d for "per day" and a for "per annum". t_per is used for tonne rates if a different time unit than that used for barrels is desired. mlt specifies whether to convert barrels, thousands of barrels, millions of barrels, billions of barrels or trillions of barrels.
Quantities, Units and Symbols in Physical Chemistry, also known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants , tables listing the properties of elementary particles , chemical elements , and nuclides , and information about conversion ...
Stack Tank Oil (STO) density (or API) may also be used by regulatory bodies to classify oil and oil products. Other properties such as Molecular Weight , saturated aromatic resin and asphaltene (SARA), refractive index , wax appearance temperature, asphaltene precipitation, and acid number , are also specified at Stock Tank conditions.

Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
That translates to oil import prices of about $79 per barrel in 2030, higher than where fossil fuel is currently trading. But under the scenario where the world reaches net zero emissions mid ...

Bottom line. Ultimately, whether you can retire on less than $1 million will largely depend on your spending needs during retirement and your remaining life expectancy.
