For example, a series of (1000, 100, 10, 1, 0.1, 0.01, 0.001) instead of (16, 8, 4, 2, 1, , , , , , ). Thus the word may refer to: Decimalisation of currencies Decimalisation of physical measurements (such as distance or weight), intimately bound historically with metrication Decimalisation of time units Decimalisation of the time of day via decimal time systems Decimalisation of the calendar via decimal calendar systems
