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
网速中的“KB”“MB”“s”等字母都是啥意思，读啥，比如兆这样？ 但是，计算机使用的并不是整1000倍，而是1024倍（2的10次方），所以为了区分，规定，计算机使用的这个1024倍的倍数要加个i，成为Ki，Mi，Gi，Ti，比如应写成1 KiB，但并没人理他，约定俗称的，一般不会引起误解。 KiB 是 ki lo bi nary byte 的缩写 Kibibyte 的缩写
