Unit Conversion and Scientific Notation

In this video tutorial, Lance from English Board Biochem TV demonstrates how to solve two-step unit conversion problems using dimensional analysis. The video includes two examples: converting micrometers to kilometers and milliliters to picoliters. Lance explains the process of using conversion tables, canceling units, and adjusting exponents to achieve the correct scientific notation. The tutorial encourages viewers to practice the second example independently before reviewing the solution.
