Ive noticed this strange thing banking executives like to do and it pisses me off. They use the roman numeral of M (for 1000x) to abbreviate whereas most people have come to accept 'K' as the abbreviation for thousand.

When I see someone write "100M" I think one hundred million dollars, not a paltry $100,000. However, they would use the number "$100MM" for one hundred million.

I must admit that it probably depends on your perspective. Since this is a tech board and Ive spend at lot of time on them, "k" was the abbreviation for "kilo(byte)", which became short for 1000x.

Now I just need to convince the banking industry to drop the M's and embrace the K!

:colbert:

The opposite perspective is k is relatively new and only used by laymen. K is not the accepted standard abbreviation for thousand. Never has been, never likely will. M and MM have been used for an extremely long time in the accounting/banking/fiance industries.

"Became" short? It's been that way since the 1790s, when the metric system was invented.

Every scientist in the world for hundreds of years disagrees with you on that score.

Fine, techically "dollars" aren't an SI unit, but SI prefixes are too convenient to ignore.

k had been a standard for a very long time. Eg km, kg, kJ...
Meanwhile MM is actually 2000 by Roman Numerals...

M and MM are pretty standard at work here, but I use 'k' in my daily, non-work stuff.

Sorry, I'm going with standard SI prefixes on this one. "k" is the correct answer. "M" and "m" (and "mm", in multiple ways...) have too many other uses.

Not to mention, in my industry, mmBtu (the stupidest unit ever invented) and/or Mbtu are used commonly, which would conflict.

If you doing accounting use M & MM, and also for some industries like oil & gas (Mbbl = 1000 barrels, MMbbl = 1,000,000 barrels). These abbreviations date back to the founding of some of these industries. M being mille (1,000) for Roman and far predating SI system. Yes I know MM is 2000 in Roman, but MM is short for M x M in industry usage.

If you do anything else use k & M.

As an engineer I'm used to k & M, but I've had clients request cost benefit be reported in M & MM. Oil & Gas industry for costs & crude counting almost exclusively uses M & MM. You just need to be aware of who you are communicating with. In general people try to write out thousand, million, and billion on any kind of serious report to avoid confusion despite SI snobs thinking their way is the golden path.

I read into that once. It hurt my head.
I could not stand to be someone who regularly interacted with both. I'd probably start crossing the wrong Is and dotting the wrong Ts and blow the world up or something.

um, I am an accountant and use K, as well as most of the accountants in my company, and even our outside audit agency.

I'm in the insurance industry and see M, MM and K used all the time.

As a matter of fact, looking at an account right now where a broker listed the limits requested at $50M and needs a quote for $15M excess $50k.
So that's a $15 million limit with a $50,000 deductible.

My boss just emailed me about it and referred to the limit as $15mm.

All depends on the person sending it. I find my colleagues in London use mm instead of M. Americans use M and K.

I disagree, I've seen people say 10k, or 100k quite often, I've never seen someone write 100m or 10m unless they were referring to millions

I am an "accountant" and I always have used K for thousand and M for million.
