Many people get confused by these letters when they first start looking at charts on a trading platform. Today, I will give a simple overview of the most common counting units used in exchanges.

1K stands for 1k, which should be easy to understand. If you see a trading volume of 100K for a certain coin, it means 100k. In New Taiwan Dollars, 1K is roughly around 30 TWD, but the exact amount depends on the current exchange rate.

1M is 1 million, and this unit often appears when looking at trading pair transaction volumes. For example, if a trading pair's volume today is 5M, it means 5 million.

1E represents 100 million, and the numbers start to get larger. You will often see this unit when looking at market capitalization or large transfers.

1B is 1 billion, and this is most commonly seen when viewing the market cap of mainstream coins. For instance, if a project’s market cap reaches 2B, that’s a scale of 2 billion.

1T is one trillion, which is the largest unit. Only top-tier assets use this unit, such as Bitcoin’s market cap sometimes being calculated in trillions.

The fastest way to remember these units is to watch the charts on exchanges frequently; over time, you'll naturally get used to them. Next time you see these letters, you'll know exactly what they mean.
