Note: In spite that the G<strong>en</strong>eral System of Measurem<strong>en</strong>t Units stablished in México<br />
utilizes “M” as a multiple equal to 10 6 as it is shown in the first table of this page,<br />
the oil industry, in the practice, has used “M” as it is shown in the second table of<br />
the same page, with a value of 10 3<br />
. Both conceptions are valid within their own<br />
contexts for internal use.
