Understanding standard units of measurement is crucial for quantifying attributes like length, mass, and time. The metric system, with units such as meters, kilograms, and seconds, is used globally, while the imperial system is prevalent in the U.S. This overview covers the importance of precise measurement in construction, navigation, science, and daily life, as well as the practicality of non-standard and compound units.
