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:
“The more specific idea of evolution now reached is—a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter.”
—Herbert Spencer (1820–1903)
“But I saw the little-Ant men as they ran
Carrying the world’s weight of the world’s filth
And the filth in the heart of Man—
Compressed till those lusts and greeds had a greater heat
than that of the Sun.”
—Dame Edith Sitwell (1887–1964)
