Yes. I eventually noticed my mistake and corrected it. 👍Thanks for pointing it out.

Hour isn’t the SI unit for time, but it is still accepted as a non-SI unit within the metric system.

What do you mean? I wrote cubed as ^3 throughout the entire explanation.

And in some cases, using metric would simply be worse in daily life.

No?

Like using Kelvin instead of Celcius

They are the same thing. They just use different starting points.

meters per second instead of kilometers per hour

Meters per second and kilometers per hour are both the same system, called the metric system.

seconds in general instead of hours and days

What are you on about? Seconds, hours and days are all part of the same system.

Fun fact: The fuel consumption of a car that needs 10 litres / 100 km (24 miles per gallon) could be simplified to 0.1 mm2

Actually yes. 10 L = 10 dm^3 = 10 000 cm^3. That means 10 L / 100 km = 10 000 cm^3 / 100 km.

To simplify further:

10 000 cm^3 / 100 km =

10 cm^3 / 100 m =

0.1 cm^3 / 100 cm =

0.001 cm^3 / 1 cm =

0.001 cm^2 =

0.1 mm^2

Is it metric? Yes. Is it practical? Not really.

It was already metric from the start before any mathematical simplification was done, so the metric system was definitely practical here.

Is the simplest mathematical form always the same as the simplest practical form? Definitely not, but that has nothing to do with the metric system.

I just downloaded it for the first time and I’m currently using it to type this comment.

It will take some practice to get used to this. 😅 Thanks for the recommendation.

I haven’t been a moderator for any community on Lemmy, so I don’t know if this feature already exists or not, but I think it would be very useful for moderators to be able merge communities. Users from the old communities should be automatically subscribed to the newly merged one, while the old communities gets removed.

This requires some way for mods to send merge request to mods in other communities, and for those mods to accept that request if they want to.

Every unique post should of course remain unchanged in the new merged community, with all its votes and comments intact. Duplicate posts however should always get merged if they belong to the same user, meaning that now the merged post will likely have more comments and votes than any of the posts it was merged from.

There should also be an option for mods to move a community to a different server.

With this, we can make Lemmy much easier to navigate for it’s users by merging multiple similar communities while also increasing the activity in those merged communities since they will now have more users.

Since Lemmy is still growing, a lot of the infrastructure isn’t in place yet. This means communities will exist on servers available at the time of their creation rather than the more suitable server for that community that might show up in the future. Ability to migrate communities (and users) from one server to another is essential for Lemmy to stay decentralised.
