Newcomers to exchanges often see various numerical units labeled, such as 1K, 1M, 1E, 1B, 1T. What do these abbreviations actually represent? It's quite simple: 1K equals 1000, 1M equals 1 million, 1E equals 100 million, 1B equals 1 billion, and 1T is a trillion. These are internationally recognized counting standards. Especially with 1T being the largest unit, representing trillion-level figures, it is usually used on exchanges to indicate the total trading volume of trading pairs or the market cap range of certain large cryptocurrencies. Mastering these basic units can help you quickly understand the scale of various data on exchanges.
