Related to specific gravity: Specific weight

gravity

 [grav´ĭ-te]
1. the phenomenon by which two bodies having mass are attracted to each other.
2. the gravitational attraction near a large body having mass, particularly near or on the surface of a planet or star.
specific gravity see specific gravity.
standard gravity (€g) the acceleration due to gravity at mean sea level, 9.80616 meters per second squared.

specific

 [spĕ-sif´ik]
1. pertaining to a species.
2. produced by a single kind of microorganism.
3. restricted to a particular structure or function, such as in application or effect.
4. a remedy specially indicated for a particular disease.
5. in immunology, pertaining to the special affinity of antigen for the corresponding antibody.
specific gravity the weight of a substance compared with the weight of an equal amount of some other substance taken as a standard. For liquids the usual standard is water. The specific gravity of water is 1; if a sample of urine shows a specific gravity of 1.025, this means that the urine is 1.025 times heavier than water. (The normal specific gravity of urine is 1.003–1.030.) Specific gravity is measured by means of a hydrometer.

spe·cif·ic grav·i·ty (sp. gr.),

the weight of any body compared with that of another body of equal volume regarded as the unit; usually the weight of a liquid compared with that of distilled water.

specific gravity

Lab medicine A measure of the solutes in a fluid; SG is detected in the urine, based on the response of a polymeric acid to surrounding ions. See Dipstick. Cf Nitrites Nephrology The SG reflects the kidney's ability to concentrate urine: if a random urine specimen has an SG > 1. 023, the kidney's ability to concentrate is assumed to be normal ; SG ↑ in SIADH, uncontrolled DM, proteinuria, eclampsia and obstructive uropathy and ↓ in renal tubular damage, chronic renal insufficiency, diabetes insipidus, malignant HTN Occupational safety A physical parameter of a liquid that indicates how heavy it is in relationship to air–≤ 1.0 = lighter than water; ≥ 1.0 = heavier than water, a datum of interest to OSHA, which requires listing of SGs in its Materials Safety Data Sheets

The purposes of this study were (i) to estimate broad-sense heritability for resistance to IHN, yield, and specific gravity in 19 clones (4 cultivars and 15 advanced selections from the USDA-ARS potato breeding program in Beltsville, MD); (ii) to determine the importance of clone x environment interactions on IHN, yield, and specific gravity; (ii) to determine the stability of resistance to IHN, yield, and specific gravity in these clones; and (iv) to determine the relationship among IHN, yield, and specific gravity.
