You might not put a lot of thought into your abbreviations, and that’s okay. However, there are official abbreviations out there that you might come across, and it would help to know about them. We’ll explain the correct abbreviation for “million” in this article.
“M” vs. “MM” – What Is The Correct Abbreviation for “Million”?
“M” and “mm” are both correct abbreviations for “million.” It’s much more common for “M” to be used (with a capital letter) because it literally translates to mean “million.” “MM” actually stands for “thousand thousand,” which allows you to multiply the numbers together.
“M” is the official abbreviation used whenever a million units of something are requested.
“mm” (which is usually kept in the lower case) is an old-fashioned abbreviation that doesn’t see much common usage. You’ll find that it’s mainly used in the energy sector, but it otherwise doesn’t get recognized.
“mm” is correct because of the Latin term “Mille.” “Mille” means “thousand,” and we can use “mille mille” to mean “thousand thousand.”
On the surface of it, “thousand thousand” might not make much sense. However, it is possible to multiply the numbers together, which is all you would need to do when it comes to creating one million (i.e. 1,000 x 1,000 = 1,000,000).
What Does “M” Mean?
“M” is the most common abbreviation for “million.” If you’re going to abbreviate “million,” it would usually turn into this form. It makes the most sense considering that “million” starts with the letter “M.” Most abbreviations follow this standard practice.
However, it’s fairly uncommon for “Million” to be abbreviated outside of scientific circles. Most native speakers wouldn’t care much about “million” as an abbreviation because they won’t often come across the number in their daily lives.
You might see it used like this:
- That’s going to be $100M. I think you should seriously consider going through with this one before signing anything.
- We have 50M units ready to roll out. Do you think there’s enough interest out there to get all of our targeted margins?
- I want to see $20M invested in this right away. I have a good feeling about all of this, and I’m sure you’ll do the right thing here.
- It’s not going to pass the 55M threshold. We’ve done everything we can, but there doesn’t seem to be a way to sort this out.
- What can I get for the £10M I have here? I know you’ve got something good for me. I can see it in your face!
“M” is only used as an abbreviation when talking about a lot of money or in scientific communities. Generally, you will not come across a “million” of anything.
What Does “MM” Mean?
“MM” is an old-fashioned abbreviation, but it still sees some usage today. You might come across “mm” in scientific or engineering fields, where different values are required, and they can reach well into the millions as a unit.
“mm” is often left uncapitalized (though there are no specific rules that state which way it should be written). It is Latin for multiplying one “thousand” by itself to create the “million” number.
- What’s the damage, then? How much $mm will I have to hand out before all of this blows over?
- That’s a lot of mm units. I didn’t realize it was going to go up by that much so quickly. What can we do?
- mmBtu is an old-fashioned measurement in physics. It was meant for energy, but it isn’t used much today.
- The budget is somewhere around $400mm, and there isn’t much sway with that, I’m afraid.
- We have managed to find 300mm units of energy, which should be more than enough to get this experiment going.
