Witryna18 sty 2024 · The ISU (or, more often, just SI) only lists fundamental units (base units). All the rest of the quantities are derived from it by combining them, for example area is length squared and volume is length cubic. But other examples include force (mass times length divided by seconds squared), energy (force times length), and so on. WitrynaThere are several ways to write most derived units. For example: meters per second can be written as m/s or m s -1. It is important to note that only the latter, m s -1, is accepted as a valid format. Therefor, …
