May I suggest OB for Ounce Byte, or 28.35 Byte, one 16th of a PB PoundByte which is 453,6 Bytes.
These measures are both practical as freedom units because it's base is close to 28, which is clearly more suitable than 32 as a freedom unit base number, and the Pound Byte can be easily halved 4 times to make an Ounce Byte. Which makes it about as convenient as other freedom units.
Finally someone is making sense. I was getting depressed with all the logical metric inspired units disguised as jokes everywhere in this thread. You get it. Thank you 🙏
