The logic was that M is the roman numeral for 1, So 5MM is 5 thousand thousand. It took a little getting used to but it kind of makes sense. I used those abbreviations until I wrote this blog post and read all the comments. Since then, I have spelled million because it seems as though the opportunity for confusing readers is pretty high.
I worked for a large American chemical company, and they also used this confusing terminology. I thought we abandoned roman numerals for industry and commerce once the zero had been invented in India. Apart from historical uses e. Beyond that, if you have a young HR professional doing the first review of your resume, they might not understand it all. How would you write out large numbers for currency?
Good comments about common usage in the US and other countries — and the emphasis on clear communication being the standard. Communication is the goal. Best to understand your audience. In the US banking industry, using M as an abbreviation for thousand and MM for a million is standard at least based on my 30 years of experience.
Using M for million in that industry could be misleading. How can MM or a million million will be a billion? Different countries and industries have different conventions. Not all of them make sense to me either. Extremely informative!! Thank you for always giving great insight into important topics Donna! Candidly, for my resume clients who are lawyers and hybrids general counsel and executives , I use M for million, and K for thousand. It is mostly to save space and for easy readership.
I really appreciated the insight and comments from others. Spelling million, billion, and trillion out helps non-financial readers understand the resume more easily. Thanks Donna! Probably because I have a bag full of space-saving tricks for writing resumes. Thanks you, Donna, for the explanation from a few years ago.
Informally we use K for a thousand and M for a million. I just happen to google it since I saw it on a letter the VP asked me to proof. My suggestion is, lets decide what we are going to use globally so everyone understands and leave it at that so there is no confusion. Honestly I think global unity is very unlikely. And before everyone gets upset just remember these numbers existed well before the war of independence.
What world do you live in?! When writing and reading documents e. I work with German and English as a translator and there is plenty of room for confusion, so I am all for solutions that make things extra clear. Well… consider yourself added to my blogroll. I have like six other blogs I read on a weekly basis, guess that number just increased to seven!
Keep writing! That was the last time I saw MM. If we write MM none of our clients know what that means and they think we made a goof. We gave up defending MM a long time ago. We use M to represent millions and K for thousands. While you are correct, I feel most of industry writes it as M. Because conventions vary between industries and regions, I like spelling million, billion, and trillion out.
Well, in the U. Ten: 10 1 zero Hundred: 2 zeros Thousand: 3 zeros Ten thousand 10, 4 zeros Hundred thousand , 5 zeros Million 1,, 6 zeros Billion 1,,, 9 zeros Trillion 1,,,, 12 zeros Quadrillion 1,,,,, 15 zeros Quintillion 1,,,,,, 18 zeros Sextillion 1,,,,,,, 21 zeros Septillion 1,,,,,,,, 24 zeros Octillion 1,,,,,,,,, 27 zeros Nonillion 1,,,,,,,,,, 30 zeros Decillion 1,,,,,,,,,,, 33 zeros. Reference to sets of zeros is reserved for groupings of three zeros , meaning they are not relevant for smaller numbers.
We write numbers with commas separating sets of three zeros so that it's easier to read and understand the value. For example, you write one million as 1,, rather than As another example, it's much easier to remember that a trillion is written with four sets of three zeros than it is to count out 12 separate zeroes. While you might think that that one is pretty simple, just wait until you have to count 27 zeros for an octillion or zeros for a centillion.
It is then that you will be thankful that you only have to remember nine and sets of zeros, respectively. The number googol termed by Milton Sirotta has zeros after it. Here's what a googol looks like, including all of its required zeros:. Do you think that number is big? How about the googolplex , which is a one followed by a googol of zeros. The googolplex is so large it doesn't have any meaningful use yet—it is larger than the number of atoms in the universe.
In the United States—as well as around the world in science and finance—a billion is 1, million, which is written as a one followed by nine zeros. This is also called the "short scale. There is also a "long scale," which is used in France and was previously used in the United Kingdom, in which a billion means one million million. According to this definition of a billion, the number is written with a one followed by 12 zeros.
The short scale and long scale were described by French mathematician Genevieve Guitel in Smith, Roger. Share Flipboard Email. Anne Marie Helmenstine, Ph. Chemistry Expert. Helmenstine holds a Ph. She has taught science courses at the high school, college, and graduate levels.
