Many beginners get confused by these letters when viewing charts on an exchange. Let me organize the most common counting units—once you see them later, you’ll understand instantly.

The units you often see on exchanges are basically these: 1K means 1000, 1M is 1,000,000, 1E is 100,000,000, 1B is 1,000,000,000, and 1T is 1,000,000,000,000. These are especially common when you’re looking at trading volume, market cap, or capital flow.

For example, if you see a certain coin’s daily trading volume is 5M, that means 5,000,000. If a project raised 2B, that means 2,000,000,000. The question of how much 1K is really depends on the scenario you’re using it for: if you’re looking at price fluctuations of a trading pair, 1K means 1000 yuan or 1000 USD; if you’re looking at trading volume units, 1K represents 1000 contracts or 1000 coins.

In real trading, the most commonly encountered units are M and B, because most trading pairs’ daily trading volumes are in the range from millions to tens of billions. The next time you see these letters, just match them to the unit conversions—you’ll get used to it quickly.
