The specific weight (also known as the unit weight) is the weight per unit volume of a material. The symbol of specific weight is γ (the Greek letter Gamma).

A commonly used value is the specific weight of water on Earth at 5°C which is 62.43 lbf/ft3 or 9807 N/m3.

The terms specific gravity, and less often specific weight, are also used for relative density.

Famous quotes containing the words specific and/or weight:

    Most parents aren’t even aware of how often they compare their children. . . . Comparisons carry the suggestion that specific conditions exist for parental love and acceptance. Thus, even when one child comes out on top in a comparison she is left feeling uneasy about the tenuousness of her position and the possibility of faring less well in the next comparison.
    Marianne E. Neifert (20th century)

    Europe has lived on its contradictions, flourished on its differences, and, constantly transcending itself thereby, has created a civilization on which the whole world depends even when rejecting it. This is why I do not believe in a Europe unified under the weight of an ideology or of a technocracy that overlooked these differences.
    Albert Camus (1913–1960)
