What is 1M on the exchange? A detailed explanation of common numerical units

In cryptocurrency exchanges, whether viewing coin prices, market capitalization, or trading volume, we often see numbers marked with letters like K, M, E, B, and T. These units may seem mysterious, but they are actually designed to make large numbers more concise and readable. Learning these units can help you understand market data more quickly.

From Thousands to Trillions: Why Exchanges Need These Units

The numbers in exchanges are often very large—one cryptocurrency’s market cap can reach tens of billions or even hundreds of billions. Writing out the full numbers every time not only increases the chance of misreading but also takes up screen space. Therefore, exchanges have adopted this standardized unit system, allowing traders to quickly assess the scale of data at a glance.

Correspondence of Units: Complete Conversion from 1K to 1T

Here are the five most common counting units in exchanges and their corresponding values:

1K = 1,000 (thousands)

1M = 1,000,000 (hundred thousand, also called million)

1E = 100,000,000 (hundred million, also called yi)

1B = 1,000,000,000 (billion)

1T = 1,000,000,000,000 (trillion)

For example, if you see a cryptocurrency’s market cap labeled as “2.5B” in the exchange, this means 2.5 billion. If labeled as “500M,” it represents 500 million. The conversion at the 1M unit is particularly useful—many emerging tokens have total market caps in this range, so 1M often appears in data displays of mid to small-cap cryptocurrencies.

Once you master this system, you will be able to read trading data more agilely and make more timely judgments in a rapidly changing market.
