Many beginners get confused by these letters when checking charts in an exchange. I’ll briefly explain the most common counting units used on exchanges.

1K represents 1,000—this is the most basic. If a cryptocurrency’s price is 1K, then when you convert it to TWD you can roughly look at the current exchange rate, but 1K itself is a fixed quantity unit. 1M equals 1,000,000, which is especially commonly used when discussing project financing or trading volume. 1E is 100,000,000, 1B is 1,000,000,000, and 1T is 1,000,000,000,000. These units often show up when people discuss total market cap or large transfers.

In fact, this counting system is used worldwide in financial markets, not just in crypto exchanges. When you’re looking at market data, trading volume, or open positions, you’ll often see these abbreviations. Especially when numbers are very large, using units like 1K, 1M, and 1E makes things much clearer—otherwise, a bunch of zeros can be visually overwhelming.

For example, if a project raised 5M USD, that means 5,000,000 USD. If an exchange shows that its daily trading volume is 2B, that means 2,000,000,000 in trading volume. If you understand it this way, the next time you look at the data, you won’t feel lost.
