Hardware Understanding 3DS Block Size

[gamecaptor]

Hi all,

I found this conversion for 3DS block file size:

128kb = 1 block
1mb = 8 blocks
1gb = 8,192 blocks

Helpful Equations:
Blocks10248 = GB
Blocks8 = MB
Blocks128 = KB
GBx1024x8 = Blocks
MBx8 = Blocks
KB128 = Blocks

I'm making the assumption this is accurate, so that said if my 3DS says I have 547,111 free blocks then it would mean I have:

547111 / 8192 = 66.79 GB of free space on my SD card?
