Yes. By standard I mean that nanometers ("nm") is used to describe physical distances. That's it's normal use, understood by all engineers. That's also how it was born into the semiconductor domain. In that domain, it should have either stayed a description of physical distances, or been replaced. They could invent codenames, or start using a better (physical) metric, if this one is no longer relevant.
