A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

How come people say 5,000 km and not 5 Mm?
why not just say millions of meters or Mega meters?

Not much need to use Mm, it doesn't come up very often. So when it does it's easier to use thousands of km so as to not confuse people with "another" measurement.

We routinely count vehicle odometers in thousands of kilometers, AKA Megameters. I'd say it's a common enough measurement to popularize Megameters

That really doesn't come up often enough.
