Weight A measure of the force exerted on an object by gravitational forces Area A measure of the extent of a surface Volume A measure of the amount of space occupied by an object Cubic meter SI system unit of volume Liter A volume equal to that of a cube whose sides are 1dm or 10cm in length. A liter equals 1.06 quarts Conversion factor A ratio that specifies how one unit of measurement is related to another unit of measurement Dimensional Analysis A general problem-solving method in which unit associated numbers are used as a guide in setting up calculations Density The ratio of the mass of an object to the volume occupied by that object. Density equals mass over volume Equivalence conversion factor A ratio that converts one type of measure to a different type of measure Equality conversion factor A ratio that converts one unit of a given measure to another unit of the same measure AuthorAnonymous ID269258 Card SetChapter 3 Vocab.txt DescriptionUnit Systems and Dimensional Analysis Updated2014-04-05T01:43:54Z Show Answers
