Metric System, An Explanation

TL;DR

An overview of base units and prefixes in the metric system explained with examples and scientific notation.

Transcript

okay as you can see in today's BM is gonna go over a quick introduction to the metric system and the following videos we'll do some dimensional analysis and unit conversion and some calculations with the metric system but this is just a short introduction I looked online and I think I got that Wikipedia this is what the Wikipedia said was the base ...
