My 2 cents to some of the really good comments already mentioned.
1kg is 2 US lbs +10%.
Learn what 10cm is, use that as base for small stuff
Learn a stride that's 1m.
1m is approx 3ft
Get a good scale in grams
Celcius is linear, Fahrenheit is not. Hence 0 freezing, 100 boiling, 50 is exactly half that amount of energy.
Now if you're into engineering I'd recommend you grab yourself a caliper and measure some of the common products you can buy. You'll notice that anything in 16th, 32th or even 64th is a most likely an approximation to a perfect size in mm.
It's important to realize that the US is the only real producing country in the world using US customary. Relatively speaking there's very little actual manufacturing being done in true US customary.
Years ago I flew transatlantic and just before landing I got up and brushed my teeth with a tiny travel set. I still remember all the people looking at me with my toothpaste and brush in hand thinking "why didn't I think of that?"
It really depends how you define reliability. SD cards are physically nigh indestructible, but can show failure when overwritten often. Hence for one off backups it's actually a good alternative. It will start showing problems when used as a medium that often writes and overwrites the same data often.
I would recommend backups on SD cards in an A/B fashion when you want to give a backup to someone else to store safely.
Back in the day I bought a fridge freezer combo, second hand, no handles. Used to be a built in model. As handles I used two magnets from full height drives, they were ludicrously strong and shaped like a little bit like a handle.
Full height drives were 3.25" high for those who are wondering.
You can read measurements without going to the device itself, instead, you use a phone or similar. This also means that a device doesn't require a display. Consider an outside thermometer as example. Home automation allows you to draw a little graph giving you a good idea how cold it got. Let's add another measurement device, say a radon meter. Again, no display needed and you could stick it somewhere less accessible.
You can make home automation as silly or useful as you want it to be.
Curious, you might want to look into what is generating your data then first. It's very easy to generate data, it's a lot harder to only generate and keep useful data.
I"d argue along that division in a democracy only is a strength if there's enough division to warrant coalition. Without enough division it can become an us versus them game with neither side willing to find common ground.
Consider running HA in a light weight systemd-nspawn container with minimal debian. No docker, only install the repositories you need. HACS if needed. Run your own database on the side somewhere and let HA use it.
