I just realized that many new users on the exchange often get confused by these symbols. Actually, it's quite simple, 1K means 1k, 1M is what? It's one million (one million units), then 1E is 100 million. Next is 1B = 1 billion, and 1T is 1 trillion. This is often used when looking at trading volume or market cap of coins. The first time I saw these numbers, I was a bit overwhelmed, but after understanding them clearly, reading charts becomes much easier. Anyone new should note this down; it will be very useful when tracking the market.
