why where new measurements created to describe a genome?

So DNA is made of your four bases (abbreviated A, G, T & C) paired with their counter part.
Genomes are very big. The human genome contains 3 billion base pairs!
When we talk about genes, or regions of a genome, it gets hard to say "this genes is 4 thousand base pairs long" or "this chromosome is 40 million bases pairs big" all the time; hence, we abbreviate using "kilo" (meaning 1 thousand) and "mega" (meaning 1 million).
So, "this chromosome is 40 million bases pairs big" can be simplified to "this chromosome contains 40 megabases". Makes sense?
