In practice, find the quantity with the fewest number of sig figs. In the example below, the quantity with the fewest number of sig figs is 27.2 (three sig figs). Your final answer is therefore limited to three sig figs. (27.2 x 15.63) 1.846 = 230.3011918 (this is what you calculator spits out) In this case, since your final answer it limited to three sig figs, the answer is 230. (rounded down)
SI derived units. Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units. Examples of such SI derived units are given in Table 2, where it should be noted that the symbol 1 for quantities of dimension 1 such as mass fraction is generally omitted. For ease of understanding and convenience, 22 SI derived units have been given special names and symbols, as shown in Table 3.
