SmartEnum VS UnitsNet

I agree SmartEnum is my go-to for this

If we knew more about these methods and what kinds of parameters they take we could maybe make some suggestions. There are some patterns like smart enum that are sometimes just the thing.

In C# I am not able to add constructors, properties, and methods. although there is a library to do this https://github.com/Ardalis/SmartEnum but wouldn't be nice if we have this feature built-in to C#.

You can use the SmartEnum library.

If engineering/scientific projects appeal to you, Units of measurement implementations for Java are woefully behind when compared with the likes of UnitsNet for C#.

Check out EngineeringUnits (https://github.com/MadsKirkFoged/EngineeringUnits), or UnitsNet (https://github.com/angularsen/UnitsNet)

https://github.com/angularsen/UnitsNet is sort of an extreme example of this, and their https://github.com/angularsen/UnitsNet/blob/master/Common/UnitDefinitions/Length.json gives an example of how to allow multiple names for units.

Just FYI: https://github.com/angularsen/UnitsNet

(I occasionally use https://github.com/angularsen/UnitsNet/, but it's not quite the same as doing it at the compiler level.)

UnitsNet does this for common units of measure, and for a more general solution, there's also ValueOf

Have you looked into using UnitsNet instead of rolling your own physical quantity library? I've used it before and it's pretty nice.

What would be best is if there was a library to use to convert things to and from measurements. This was what I first attempted, using The UnitsNet library. This library is excellent, and I recommend it to many people. The issue I have with it, is that it was far more in depth than what I need it to do.
