二進位轉十六進位轉換器
將二進位數轉換為十六進位。對於相同的值，十六進位比二進位精簡 4 倍。
如何使用本工具
- 1
Type or paste your binary digits into the input box. Whitespace between groups is fine and gets stripped automatically.
- 2
Read the uppercase hexadecimal result in the box below, which updates instantly as you type.
- 3
Copy the hex value out for use in your code, config, or documentation.
什麼是二進位轉十六進位轉換器？
二進位使用二進位（數字 0 和 1）；十六進位使用十六進位（數字 0-9 和 A-F）。每個十六進位數字恰好對應 4 個二進位數字，因此十六進位是書寫大型二進位數字精簡得多的方式。這種轉換是程式設計、偵錯記憶體傾印以及閱讀機器碼的基礎。
