Chem – LESSON 3: Metrics and Conversions


What is this lesson about?

This lesson is about the units of measurement chemistry uses and how you can use those units to covert between each other. It also includes and introduction to skills in how to solve word problems, which very often contains the units talked about in this lesson. This problem solving work will also continue throughout many of the chapters but it starts here.


Why is it critical to understand?

Perhaps the most critical science requirement is understanding between two or more people. This is why the scientific units were created. They were meant as a universal language to discuss scientific concepts with other people searching the same kinds of questions. That way any person from any language can analyze mathematical work in science and understand what the person is trying to describe as long as they understand the units. The language of metric units is a language that was created and didn’t come from any natural source. Many people have criticized it and some of those criticisms are very true. However, before this metric system came along most systems of scientific measurement and calculations were much, much worse. Therefore, the metric system is a vast improvement. The sections on problem solving and conversions some of the most common ways that you will see the metric system used. It is nice for a student to be able to identify the metric system, but being able to use the metric system is more important.
