Recently, a friend asked me what those letters on the exchange represent, and I realized that quite a few beginners are not very clear about these counting units. Actually, the unit system on exchanges is quite simple; once you understand it, you can interpret market data more intuitively.

Let's start with the smallest. 1K means 1k, which most people know. Then 1M is 1 million, or 1,000K. Next is 1E, representing 100 million, which is 100 times 1 million. 1B is 1 billion, or 1,000 million. The largest is 1T, representing 1 trillion, or 1,000 billion.

Why do you need to understand these? Because when looking at exchange data, especially trading volume, market cap, or capital flow, you often see these units. For example, if a certain coin's daily trading volume is 5B, that means 5 billion in trading volume. If a project's total market cap is marked as 1T, it indicates that the project is valued at the trillion level.

Mastering these unit conversions allows you to understand market data more quickly, without having to do calculations every time. Especially during rapid market fluctuations, being able to quickly interpret the magnitude of numbers is quite helpful for making trading decisions. Next time you see these letters, you'll be able to tell exactly how much they represent at a glance.
