Or even better, just use angstrom, which is 1/10 of a nanometer. So you go from 1nm to 9Å. Plus it sounds cool and scientific and it's actually not (total) marketing bullshit.
It wouldn't, but marketing based on an objective metric is better than inventing metrics or tying them to abstract concepts like a carbon tax (a carbon tax is a banker's solution to global warming, ie how can we profit from it).
The (total) qualifier was just because I realize node sizes are measured slightly different depending on the foundry, ie TSMC and Intel mean different things when they say 10nm.
