Recently, some beginners asked me what those units like K, M, E, B, T in exchanges actually mean, so I might as well organize it here.

Actually, these are abbreviations for numerical counts, often encountered when viewing charts on exchanges. 1K is 1k, which should be easy to understand. 1M represents 1 million, and you'll see the M unit when looking at trading volume. 1E is 100 million, used for large contracts or futures holdings.

Beyond that is 1B, representing 1 billion, a unit used when looking at large institutional holdings or market capitalization. Finally, there's 1T, which is 1 trillion, a very large number. For example, Bitcoin's market cap sometimes is calculated in 1T, and it has even surpassed the 1T mark at its peak.

Honestly, when I first entered the scene, I was also confused by these units, especially when looking at trading software, with a bunch of numbers flying by that I couldn't keep up with. Later I realized that these are just for quick reading, so you don't have to count zeros one by one. Especially when dealing with data at the 1T level, saying 1T is definitely clearer than saying 1M,000,000.

I suggest beginners memorize this, because these units frequently appear when trading, viewing K-line charts, checking holdings, or market cap. Once you grasp this logic, your chart reading efficiency will improve, and you won't be overwhelmed by a screen full of numbers anymore.
