Metric Conversions and Unit Fractions

This video tutorial demonstrates how to convert weights using metric units through three examples. It begins with an introduction to metric units and conversion methods, focusing on using unit fractions. The first example converts 875 milligrams to grams, the second example converts 0.12 kilograms to centigrams, and the third example converts 258 milligrams to decagrams. Each example uses unit fractions to simplify the conversion process, and the video concludes with a summary of the examples.
