I happened to have a friend ask me this question, so I’ll just share some common units of measurement used on exchanges.

Actually, many beginners get confused by these letters when they’re looking at charts, especially when checking market cap and trading volume. Basically, they’re just different magnitude indicators.

The smallest unit, K, stands for 1,000, which is easier to understand. Then, moving up, 1M means one million, which is 1M. If a certain coin’s daily trading volume is 1M dollars, it means $1 million worth of trades happened—this is quite common for smaller coins. Going higher, 1E represents 100 million, 1B is 1 billion, and 1T reaches the trillion level.

For a concrete example, if you see a project’s market cap labeled as 500M, that’s $500 million. If a major coin’s trading volume is marked as 1B, that’s $1 billion in daily trading volume. With these conversions, you can quickly gauge the size of a coin or project.

Basically, just remember this relationship: K is thousands, M is millions, E is hundreds of millions, B is billions, and T is trillions. Next time you’re looking at charts, seeing a label like 1M will immediately tell you it’s in the millions—no need to count on your fingers.
