There are several threads discussing this.
1. Apparently, you cannot have more than two decimals for typical financial software, so currency unit description normally looks like this: XXXXX(N).XX, where N can be any number with ONLY two numbers to the right of the decimal, but not XXX(N).XXXXXXXX, which is the current description.
2. In addition, there are several suggestions on how to call 100 satoshis with several possibilities outlined in the first post (you don't call dollar 100 cents).
3. A new symbol for bitcoin is proposed to ISO-XBT, because BTC is for Bhutan or some other country starting with B. Changing to XBT and AT THE SAME Time changing description of XBT=0.000001 BTC would be a simple and logical way to fulfill all requirements. There are quite a few people here who advocate this and a few also proposing to call the unit "bit".
4. I suggest that it does not really matter how to call the unit (could be bit, x-bit, ubit or microbit) as long as we agree that it would be depicted as XBT and have a value of 1XBT=0.000001 BTC (current).
