The day bitcoin reaches $100,000 per whole coin, you are going to see gasoline priced in sats everywhere you go.
In the 1792 Coinage Act, it was stated
| The money of account of the United States shall be expressed in dollars or units, dismes or tenths, cents or hundredths, and milles or thousandths, a disme being the tenth part of a dollar, a cent the hundredth part of a dollar, a mille the thousandth part of a dollar, and that all accounts in the public offices and all proceedings in the courts of the United States shall be kept and had in conformity to this regulation.
A Mill (current spelling) is a thousandth of a dollar, or a tenth of a cent and is an official denomination. Mills are used mainly when determining property taxes (3 mills per dollar value for instance), and mills are listed when you see prices at a gas station.
So when bitcoin reaches $100k - and you see “1000 sats/$” at the top of stacker news - you will also see an every day item priced in sats everywhere you go. In this images above the prices would be 1229, 1479, and 1729 Sats per gallon. Gas prices in Sats!!
