Economic Definition of cardinal utility. Defined.

Term cardinal utility Definition: A measure of utility, or satisfaction derived from the consumption of goods and services, that can be measured using an absolute scale. Cardinal utility exists if the utility derived from consumption is measurable in the same way that other physical characteristics--height and weight--are measured using a scale that is comparable between people. There is little or no evidence to suggest that such measurement is possible and is not even needed for modern consumer demand theory and indifference curve analysis. Cardinal utility, however, is often employed as a convenient teaching device for discussing such concepts as marginal utility and utility maximization.
