Method
The following method has the advantage of needing no volume information of the body (see the note about the residual volume below). The procedure is based on Archimedes' principle, using the following three measurable values: The weight of the body outside the water, the weight of the completely immersed body (a weight that may be negative if the body in question is less dense than water) and the density of the water:
Multiplying by the density of water gives

Famous quotes containing the word method:
“The method of authority will always govern the mass of mankind; and those who wield the various forms of organized force in the state will never be convinced that dangerous reasoning ought not to be suppressed in some way.”
—Charles Sanders Peirce (1839–1914)
“The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind. It is simply the mode in which all phenomena are reasoned about, rendered precise and exact.”
—Thomas Henry Huxley (1825–95)
“Argument is conclusive ... but ... it does not remove doubt, so that the mind may rest in the sure knowledge of the truth, unless it finds it by the method of experiment.... For if any man who never saw fire proved by satisfactory arguments that fire burns ... his hearer’s mind would never be satisfied, nor would he avoid the fire until he put his hand in it ... that he might learn by experiment what argument taught.”
—Roger Bacon (c. 1214–1294)
