title: Is 1KB = 1.024 bytes OR 1.000 bytes?
body: <p>Everyone keeps saying that</p>
  <pre><code>1'000 KB = 1 MB (decimal) -&gt; Megabyte (MB) 10^6 Byte = 1 000 000 Byte
  
  1'024 KB = 1 MiB (binary) -&gt; Mebibyte (MiB) 2^20 Byte = 1 048 576 Byte
  </code></pre>
  <p>But when you look at windows properties of a folder, you get:</p>
  <p><a href="https://i.stack.imgur.com/iaDKH.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/iaDKH.png" alt="enter image description here" /></a></p>
  <p>Which clearly uses 1KB = 1024bytes (and it's not this &quot;MiB&quot; but still uses 1024). So, what's the veredict?</p>
