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:
“I was asking for something specific and perfect for my city,
Whereupon lo! upsprang the aboriginal name.
Now I see what there is in a name, a word, liquid, sane, unruly,
musical, self-sufficient,
I see that the word of my city is that word from of old,
Because I see that word nested in nests of water-bays, superb,
Rich, hemmd thick all around with sailships and steamships, an
island sixteen miles long, solid-founded,”
—Walt Whitman (18191892)
“When a house is tottering to its fall,
The strain lies heaviest on the weakest part,
One tiny crack throughout the structure spreads,
And its own weight soon brings it toppling down.”
—Ovid (Publius Ovidius Naso)
