- n. The quality of being dense, close, or compact; closeness of constituent parts; compactness, actual or relative.
- n. The mass or amount of matter per unit of bulk. The mass is the ratio of the living force or double the energy of motion to the square of the velocity. Experiments made by Newton upon the effect of attaching masses of different materials to pendulums have shown that the weights of bodies are precisely proportionate to their masses; consequently, the density is measured by the specific gravity, or the weight of a unit bulk. The unit of density is generally taken as that of water at its temperature of maximum density (4° C., 39° F.) and under ordinary pressure. Inasmuch as the gram was intended to be, and within the limits of the probable error of the best observations actually is, the mass of one cubic centimeter of water under these conditions, it is follows that the density as ordinarily expressed is, as closely as possible, the number of grams in one cubic centimeter of the particular kind of matter in question. The following table show the density of several important substances: iridium, 22.4; platinum, 21.4; gold, 19.3; liquid mercury, 13.6; lead, 11.3; silver, 10.5; copper, 8.9; nickel, 8.7; iron, 7.8; tin, 7.3; zinc, 7.2; the earth, 5.6; solution of iodides of mercury and potassium, 3.2; diamond, 3.5; rock, about 2.7; aluminium, 2.6; sulphur, 2.0; magnesium, 1.7; the human body, 1.1; india-rubber, 1.0; alcohol, 0.8; ether, 0.7; lithium, 0.6; vapor of iodide of arsenic, 1.02; air, 0.0013; aqueous vapor, 0.0008; hydrogen, 0.00009.

- n. In electricity, the quantity of electricity per unit of volume at a point in space, or the quantity of electricity per unit of area at a point on a surface.
- n. In photography, opacity of the developed film of a negative.
- n. physics A measure of the amount of matter contained by a given volume.
- n. The ratio of one quantity to that of another quantity.
- n. The probability that an event will occur, as a function of some observed variable.

“The question supplies an important clue: the word "density.”
“The article does not say how the ultra high strength or higher density is achieved, I would expect it is with the addition of admixtures which can be hazardous to the environment and expensive.”
“When I asked how this could be she waxed a little wroth at what she called my density, and asked if I did not appreciate that we should have to move at any rate in a year or two in order to provide the children with a bedroom apiece.”
“He was surprised at what he called our density, and said the thing was all clear and simple to him.”
“As you remember before we got the resistivity on this log we had seen what we called a density to neutronic cross affect and if these sands had salicious or over growths of parts, that was sucking off the [frosting] then your frosting wouldn't be there.”
“There was good news on the keyword density front as searches with the word "density" in them were down (- 32. 91%).”
“(tries really hard not to call [Bill in Central District], who supports the suburbs, a NIMBY) "the myth that higher density is the solution" Pleast tell me in what way that's a myth.”
“To that end balancing sex ratios and population density is key.”
“The sea was covered by a fog, or, rather, by a pearly mist that was fog-like in density, in so far as it obstructed vision, but that was no more than a film on the sea, for the sun shot it through and filled it with a glowing radiance.”
“The blackness seemed suddenly to increase in density, and they stumbled up the beach, feeling their way to the gate.”
