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. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Posts must be original/unique
- Be good to others - no bigotry - including racism, sexism, ableism, homophobia, transphobia, or xenophobia
- Adhere to Lemmy's Code of Conduct

MODERATORS
Units closer related to everyday stuff are those that stick around. Like horse power or km. People don't use Mm but instead 1'000s of km, even into the million km for cars. Even in space they still tend to use km like for the distance to the moon or sun. Only once the distances get absurdly large is there a shift to either another unit (light years) or the use of different notation (like 3.14E12 m).
The astronomical unit AU is commonly used for things in the solar system. 1 AU is roughly the average distance to the sun, about 150 000 000 km
