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)
“as his weight wilts
and he is on a porch
that won’t hold my arms,
or the legs of the race run
forwards, or the film
played backwards on his grandson’s eyes.”
—Michael S. Harper (b. 1938)
