Files size units: KiB vs KB vs kB - User Experience Stack Exchange The consensus was: 1 kB = 1000 bytes 1 KiB = 1024 bytes The source for this was the NIST reference on SI units I would use the more technically correct KiB In other words, divide the number of bytes by 1024 and show that with KiB as the unit I doubt it's important if users mistakenly think "20 KiB" is 20,000 bytes rather than 20,480
Mac OS下储存大小的计算方式是否和Windows下不一样？ - 知乎 硬盘的容量用了1000进位而不是以2进制为底的1024进位这个问题已经是常识了，但是存储厂商这么标反而是符合标准的。可能有些朋友在Linux和macOS中见过容量单位的两个大写字母中插了一个i的，比如KiB、MiB、GiB这样的单位，那么它和我们常用的KB、MB和GB有什么区别呢？
