The endless discussion about binary versus decimal prefixes – GB vs GiB

I already wrote about this twice:

  1. My first blog post about the issue
  2. My second blog post

And to fire up the discussion once again, I found another link on the IEC website: http://www.iec.ch/si/binary.htm

Remember that scientists want to be very precise about their findings and writing G, means there’s 1,000,000,000 of whatever they were measuring. If they wanted to switch to counting in binary language, they would either switch to using 0s and 1s or use binary prefixes like Gi, Mi, Pi and Ki.

So once again:

  • 1 kB = 1,000 Bytes
  • 1 KiB = 1,024 Bytes
  • 1 GB = 1,000,000,000 Bytes
  • 1 GiB = 1,024 x 1,024 x 1,024 Bytes


Spread the word. Please!

Facilitate the conversation: say what you mean and don’t make assumptions

We all work with words every day. Words that can cause confusion if used incorrectly, but words can also make the conversation smoothless … if used correctly.

I’d like to name a few of these possible confusion from my daily experience in the IT Storage business.


  • Network versus fileserver

How many of you store their data on the network? The network connects clients to servers (or other clients). The network consists of network devices like switches, routers, bridges, firewalls and the cables to connect all these devices together. I store my data on a file server and the network helps me getting it there.
