2technical The actual magnitude of a numerical value or measurement, irrespective of its relation to other values.

*‘To obtain relative values absolute values were divided by germination percentages obtained in water, and the result was multiplied by 100.’**‘We use dBm to express absolute values of power relative to a milliwatt.’**‘Figure 4 shows five-year moving averages of the mean absolute value of the ratio of the current account balance to GDP for twelve countries.’**‘The protected polymorphism conditions are now given by the inequalities that the absolute values of these eigenvalues are larger than one.’**‘The heat peaks caused by the upward and downward pressure jumps differ in sign but should agree in absolute values.’*
