Many beginners get confused by these letters when they check price charts on exchanges. Today, I’ll break down the most common counting units used on exchanges.

Let’s start with the most basic one. **K** stands for thousand, so **1K = 1,000**. Most people should already know this. Going up, **M** represents the million level, so **1M = 1,000,000**—meaning how much **1M** is worth depends on the specific asset. But in terms of the unit itself, **1M = 1,000,000** is fixed.

Next, **E** represents the hundred-million level, so **1E = 100,000,000**. **B** represents the billion level, so **1B = 1,000,000,000**. The largest is **T**, representing the trillion level, so **1T = 1,000,000,000,000**.

In practice, when you look at exchange charts, you often see a coin’s **24-hour trading amount** shown as **“3.2B”**—that means this coin traded **3.2 billion** worth in quantity today. Or if a project’s funding amount is listed as **“5M”**, that means **$5,000,000**. Once you understand these units, you won’t be intimidated by all kinds of large numbers when reading data.

In summary, the five units **K, M, E, B, T** basically cover all the common data annotations you’ll see on exchanges. Next time you see these letters, just convert them directly—no need to look them up one by one.
