MM lb

[picasa]

MM lb/yr production rate?? - Sounds like a unit that I have not come across before. Is it true that 1 MM lb = 1,000,000 lbs.?

Roman numeral M = 1000. MM is way yo signify one-thousand 1000s... or one million. It's not a uniformly used term, but I see it in the waterworks world too.

The heat transfer arena consistently uses MMBTUH for millions of BTUs per hour.

I've seen the MM my entire career. It's a normal for expressing a plant capacity or flow rates.

A warning - in different disciplines, I've seen both M and MM used for million. For example, computer storage is expressed in MB for megabytes, not in MMB for million bytes.
