The standard units of time are established in terms of known frequencies of oscillation of certain devices. Measurements play an important role in daily life because they are useful to do basic tasks, such as take a child's temperature with a thermometer, make time estimations, measure out medicine and find weights, areas and volumes of different materials or substances. The basic units for the metric system are shown in Table 1. When we measure the distance between any two points in terms of width, thickness, depth, and height, we measure length.
