Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Are there any languages that allow units?
Julia's Unitful package is one of my favorites. https://github.com/PainterQubits/Unitful.jl
Tangentially related, LaTeX's siunitx package makes typesetting units a joy. https://ctan.org/pkg/siunitx

Similitude.jl is new more powerful Quantity than Unitful.jl
Not sure why you think more units is more powerful. Defining specific units is seldom the difficult part of dealing with units in code. I'd say that just looking at the tests for Unitful (excluding the separate tests for dates) to the tests of Similitude that there seems to be a lot more functionality in Unitful. What are the advantages of these alternate packages? And I do not think focusing on "more powerful" is too useful unless qualified appropriately.

ModelingToolkit, Modelica, and Modia: The Composable Modeling Future in Julia
It's really two separate problems but they kinda interact.
Unitful quantities with heterogeneous units don't have a `zero` function that works correctly, which gets in the way inside numerical routines. [0] There are other places where 0 or 1 is added, which is an error for quantities but not for plain real numbers. [1]
Zygote doesn't handle mutating arrays. [2]

Atlas, a (hopefully) better engineering IDE
Julia has the Unitful package [1], which does a decent job. It's quite ergonomic, and Julia's design helps with making existing code/libraries play nicely with Unitful-encoded units/values.

GNU Units
I've seen a few before, and a quick search yielded a bunch for me, right off the bat. By no means exhaustive:
Julia: https://github.com/PainterQubits/Unitful.jl
Python: https://pint.readthedocs.io/en/0.6/
C++: https://github.com/nholthaus/units
etc.
And yes, it has always struck me as strange that date/time/calendar libraries are standard as canonical libraries shipped with language distributions, but units are not.

UnitSystems.jl vs Unitful.jl
[UnitSystems.jl](https://github.com/chakravala/UnitSystems.jl) and Unitful.jl are both Julia packages that provide support for working with physical quantities and units of measurement. However, there are some differences between the two packages:
-
rounding in julia is incorrect
however, the correct solution would be for round to just work correctly instead of me writing extra methods for my packages https://geophysics.crucialflow.com/dev/units
- Similitude.jl is new more powerful Quantity than Unitful.jl
- Unitsystems.jl (complete reference for Physics Conversions)
-
GNU Units
Recently I created a library for unit conversion in Julia, which is the most complete tool for unit conversion I am currently aware of
