Summary. SI Standards In order to describe other physical phenomena, physicists have either: • Derived Units: SI … Numbers as Measurements • Numbers in math class can stand by themselves and be meaningful • In science, we need to give that number a dimension, or a kind of physical measurement, in order to make it meaningful.
