Units: mboe vs mmboe

[MichaelTiemannOSC]

We all know that "boe" is a "Barrel of Oil Equivalent".

It appears that the 'm' in "mboe" is a Roman M, meaning thousand, and that 'mm' is a Roman thousand squared, meaning a million.

Is that correct? Is 'mcf' therefore a thousand cu ft of gas? Are there other 'm's that are thousands instead of millions we need to look out for?

I will need to update our units files (which don't know this particular prefixing rule).
