insect VS uom-se

Apparently this replaces https://github.com/sharkdp/insect

You might like https://insect.sh/ ;)

For the record I use insect.

https://github.com/sharkdp/insect seems to be somewhat similar, but it's mostly for physical units. However, it's the only opensource one that is embeddable.

Insect: https://github.com/sharkdp/insect

It is a bit slow but has decent features, including some physical units support.

I set up Tilda (or another Guake equivalent; I tried a bunch of them and can’t remember on which I settled in the end) to run it automatically when a terminal is opened, when pressing Scroll Lock. It’s quite neat: when I need to do a quick calculation, I just hit Scroll Lock, which spawns a drop down terminal with the focus; then type whatever I want to calculate; then control-D to dismiss the drop down terminal and I am back in whatever I was doing without moving either hand off the keyboard.

I do more or less the same thing on my Mac with Alfred.

I'm in the same boat and will pay for Kagi, though I have a different interaction with a search engine and thought you might like the counterpoint. Notably, I don't use Google for most of what you described:

Translation: I use DeepL instead (google is doing poorly on Asian languages)

Conversion: not having much need for imperial but I use this for all unit conversion (though usually directly in my terminal): https://insect.sh/

Wikipedia: if I type Wikipedia+something my browser automatically use the wiki engine (chrome can do that too)

Word definition: on OSX I long press on the trackpad and the definition pops up (across languages, translation too for single words)

Lyrics: Spotify show them now! (admittedly that's a recent feature)

insect.sh goes up to about 109 × 1015.

Looks like it is comparable to javax.measure (https://jcp.org/en/jsr/detail?id=363). I used an implementation of that a few years ago: https://github.com/unitsofmeasurement/uom-se

It's a complex domain, especially if you get down to having more complex units composed of other units and want to do conversions between metric and imperial. In our case we were dealing with material properties (chemical, physical, magnetic, etc.) and different countries and companies using different ways to record characteristics for materials.
