for years the community have discussed the common terminology of the future
and it became apparent when the time comes that saying 'zero point zero zero" gets too irritating that we would use 'bits' (100 sats) instead

EG gallon of milk = 500bits
...
also the mbtc which is 10,000sats gets more confusing with the word Milli and Micro,, where micro is actually (ubtc) which is only 100sat

because if we started doing mbtc (10,000 sats) it wont be long before people (as you shown above) would start saying 'zero point five' for a gallon of milk or 0.1mbtc for a litre.. or "zero point zero five mbtc" for a pint of milk

so its better to skip the mbtc and go to ubtc (100 sats) aka 'bits'

the whole is a 'Mbtc' a milli or a micro. is confusing conversationally anyway.
and also milli is just a temporary thing which by the time it becomes common. its time to change again.
so much easier to just jump to 'bits' (100sats(ubtc(microbtc))) so that people can get used to on a more permanent terminology that 1 bit has 100 divisions. which most people around the world are used to
