There are two major systems of measurement used in the United States, with even more variations found around the two. The two commonly used are the Metric System and U.S. Customary System of Measurement.Answer and Explanation: The base units of the Metric System depend on what is being ...
New Definitions of SI Base UnitsThere are seven base units in International System of Units (SI). Seven fundamental physical constants have been chosen to define the base units. These are also called as defining constants.doi:10.1007/978-3-030-43969-9_5S. V. Gupta...

It follows, then, that the luminosity function has units of $\mathrm{cd}/(\mathrm{W\:sr^{-1}m^{-2}})$, and the role of the SI definition is to normalize it such that $$\bar{y}(555\:\mathrm{nm})=\frac{1\:\mathrm{cd}}{\mathrm{W\:sr^{-1}m^{-2}}}.$$ From here ...
