Not exactly my first steps, but I saw no other place to post this.

Is there a Julia package taking care of unit conversions (like converting metres to miles, etc.)?

Have a look at: Unitful

For miles you probably also want [UnitfulUS](https://github.com/PainterQubits/UnitfulUS.jl).

Thanks.

That looks like it.

Sometimes Google can help more quickly, like searching for “julia unit conversion”, which will lead you to at least two packages on the very first page 😉

Yes, that may be so.

I searched using the strings “julia” and “conversion” on the forum itself.

Just for your information, another source of information for this kind of questions is [pkg.julialang.org](http://pkg.julialang.org). (I’m mentioning it here because I think it doesn’t have the popularity it deserves)

In your case, the query “unit conversion” returns a few relevant packages (first among which is `Unitful.jl`):

[https://pkg.julialang.org/docs/search?q=unit%20conversion](https://pkg.julialang.org/docs/search?q=unit%20conversion)

  

That being said, I think posting the question on discourse is the best way to get a feeling about which packages are popular, maintained, and overall in good shape.

Thanks. That is good to know.
