  3. Volume correction factor - Wikipedia

    en.wikipedia.org/wiki/Volume_Correction_Factor

    Since API gravity is an inverse measure of a liquid's density relative to that of water, it can be calculated by first dividing the liquid's density by the density of water at a base temperature (usually 60 °F) to compute Specific Gravity (SG), then converting the Specific Gravity to Degrees API as follows: = =

  4. Baumé scale - Wikipedia

    en.wikipedia.org/wiki/Baumé_scale

    Consider, at near room temperature: +100 °Bé (specific gravity, 3.325) would be among the densest fluids known (except some liquid metals), such as diiodomethane. Near 0 °Bé would be approximately the density of water. −100 °Bé (specific gravity, 0.615) would be among the lightest fluids known, such as liquid butane.

  5. Relative density - Wikipedia

    en.wikipedia.org/wiki/Relative_density

    Specific gravity for solids and liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" (abbreviated r.d. or RD ) is preferred in SI , whereas the term "specific gravity" is gradually being abandoned.

  6. Stock tank oil - Wikipedia

    en.wikipedia.org/wiki/Stock_Tank_Oil

    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.

  7. Base conditions - Wikipedia

    en.wikipedia.org/wiki/Base_conditions

    Density correction is also performed on liquids under measurement. For instance, the sticker on gasoline pumps that states that the volume is corrected to 15 °C (59 °F, or 60 °F in the U.S.) means that the measured volume has been compensated for thermal expansion. One would otherwise get a larger mass of gasoline in a tank filled in cold ...
