使用说明与常见问题How-to & FAQ
「比特 ↔ 字节」是什么？What is the Bit to Byte tool?
1 B = 8 bit。支持比特、字节、千字节、KiB互算。1 B = 8 bits. Units: bit, byte, kilobyte, kibibyte.
如何使用「比特 ↔ 字节」？How do I use the Bit to Byte tool?
在「比特 ↔ 字节」中输入数值并选择原单位，表格会同时列出换算到所有其他单位的结果，可一键复制。Enter a value in the Bit to Byte and choose the source unit; the table shows the value in every other unit at once, ready to copy.
KB 是 1000 还是 1024 字节？Is a KB 1000 or 1024 bytes?
本页按国际单位制：1 KB（千字节）= 1000 字节；1 KiB（kibibyte）= 1024 字节，两者分开列出。1 字节 = 8 比特，所以 1 KB = 8000 比特。This page follows SI: 1 KB (kilobyte) = 1000 bytes, while 1 KiB (kibibyte) = 1024 bytes, listed separately. 1 byte = 8 bits, so 1 KB = 8,000 bits.
1 比特 等于多少其他单位？How much is 1 bit in the other units?
1 比特 = 0.125 字节 = 0.000125 千字节 = 0.0001220703125 KiB（按定义系数计算，最多保留 10 位有效数字）。本页不接受负数：输入负值会提示错误。1 bit = 0.125 byte = 0.000125 kilobyte = 0.0001220703125 kibibyte (from the defined factors, up to 10 significant digits). Negative values are not accepted here and show an error.
有哪些选项可以调整？What options can I adjust?
「比特 ↔ 字节」的设置：「数值」默认 1。每次生成结果都按当前设置处理。Settings in the Bit to Byte — "Value" default 1. The result always uses the current settings.
换算系数准确吗？Are the conversion factors exact?
「比特 ↔ 字节」采用国际单位制（SI）或公认标准中的定义值作为换算系数，结果保留约 10 位有效数字。The Bit to Byte uses factors defined by the SI or other recognised standards and shows about 10 significant digits.
「比特 ↔ 字节」免费吗？需要注册吗？Is the Bit to Byte free? Do I need an account?
「比特 ↔ 字节」完全免费，无需注册或安装，打开网页即可使用，手机和电脑都能用；输入的内容只在你的浏览器本地处理。The Bit to Byte is completely free with no sign-up or install and works on phones and desktops; what you enter is processed only in your browser.
