That's just Windows. I don't know why Microsoft still hasn't changed it, but it goes way back.

Basically, Windows measures storage in powers of 2. Instead of 1000, they use 1024. A new set of prefixes was invented just to distinguish them, so it's "gibabytes" and "tebibytes" rather than "gigabytes" and "terabytes." 1TB is roughly 930GiB.
