This package implements two specialized unit systems commonly found in cosmology. It is based on Mason Protter's [NaturallyUnitful.jl](https://github.com/MasonProtter/NaturallyUnitful.jl), a different natural unit system that uses eV as the base unit. 

For more information, read the [documentation](https://xzackli.github.io/UnitfulCosmo.jl/dev).

To generate your own conversion factors, you basically solve a linear system using something like this Mathematica code,

```

Solve[ 

 {c m/s == \[HBar]  (kg m^2)/

    s^2 s == \[Epsilon]0 A^2 s^4 kg^-1 m^-3 == 

   kb (kg m^2)/s^2 1/Kelvin == 1},

 { kg, Kelvin, s, A} ]

 ```
