When frequently watching charts on an exchange, you’ll see various letters like K, M, E, B, and T, and many beginners actually don’t quite understand what they mean. Today, let’s give everyone a quick introduction to the most common counting units used on exchanges.

First, the basics. 1K means 1,000—everyone should know this. Then 1M means 1 million, which is very important. When you’re looking at trading volume or market cap on an exchange, what 1M equals in dollars depends on which metric you’re viewing. For example, if a coin’s daily trading volume is 5M, that means a trading volume of 5,000,000 USD.

Next, 1E represents 100 million. This unit is often encountered when viewing market cap or large transfers. For instance, if a project’s market cap is shown as 2E, that means 200,000,000 USD. 1B is 1 billion, which is usually used when looking at the market caps of top projects. For example, for projects like BTC and ETH, market caps are calculated using B.

The largest unit is 1T, which represents one trillion. This is used relatively less in the crypto market, but you’ll see it when looking at the total market cap of the entire crypto market or certain traditional financial data.

In fact, as long as you remember this sequence—K is thousand, M is million, E is hundred million, B is billion, and T is trillion—when you look at any data on an exchange, you won’t get confused. The next time you check the market, you’ll be able to quickly tell how big that number really is.
