Is There a Name for a 1 Followed by a Million Zeros?

Yes, a 1 followed by a million zeros is called a millionplex in the short scale, commonly used in the United States and most English-speaking countries. More specifically, it can also be expressed in scientific notation as 10^6. In the long scale used in some parts of Europe, this number would still be called a millionplex, as it refers to 10^6.

Breakdown of Large Numbers

For clarity, let's take a look at the breakdown of this number and others:

10^6 1000000 (one million) 10^24 1000000000000000000000000 (one septillion in the short scale)

While 'millionplex' might sound catchy, it's more of a playful term used by those fascinated by large numbers. Technically speaking, a millionplex is 10 to the power of a million, but for the sake of simplicity, calling it '10 to the million' or even 'a one with a million zeros' would be more widely understood.

Alternative Names and Nicknames

For those who appreciate large numbers, other playful terms like 'millionplex' or 'googolplex' (10 to the power of a googol) might ring a bell. However, these terms are more aligned with recreational mathematics and are typically not used in everyday or scientific contexts.

There are also names like '10 tretrigintatrecentilliduotrigintatrecentillion,' which is quite a mouthful and only applicable if you or your audience is versed in medieval Latin coinages. The reason behind this name is its theoretical representation of a 10^6 yet, as the example shows, it's not practical for general use due to its complexity.

Why There Is No Common Name

Given the sheer magnitude of the number, it's unsurprising that there isn't a universally accepted name for it. Most commonly, mathematicians and enthusiasts simply refer to it as 10^6 or '10 to the million.' The problem with terms like 'millionplex' is that it's based on a smaller, more familiar number, leading to confusion and misunderstanding.

If you're talking to people who are into large numbers, they might appreciate the creative use of terms like 'millionplex.' However, for the average person or even many mathematicians, such terms are not part of their lexicon. Thus, using 10^6 or 'a one with a million zeros' would be more effective in communication.

It's important to note that for a number so large, there is no significant practical application in real world scenarios. Therefore, the term 'millionplex' or similar names might be more of a theoretical concept rather than a named constant used in actual mathematical or scientific work.

In summary, there isn't a commonly used name for a 1 followed by a million zeros, but you can use terms like 'millionplex' for fun or scientific notation for clarity. However, in most practical contexts, simply specifying the number as 10^6 or 'a one with a million zeros' is the best approach.
