```julia

julia> typeof(1.0u"kg/m^3")
Quantity{Float64, 𝐌 𝐋 ^-3, Unitful.FreeUnits{(kg, m^-3), 𝐌 𝐋 ^-3, nothing}}
julia> Quantity{Float64, 𝐌 𝐋 ^-3, Unitful.FreeUnits{(kg, m^-3), 𝐌 𝐋 ^-3, nothing}} <: Number
ERROR: syntax: missing comma or } in argument list

```

How can I get a string representation of a unitful type in a such way that it can be parsed back by Julia? For other types it was as simple as `string(Symbol(T))`

Fyi, your question seems to be related to [this open Unitful.jl issue](https://github.com/PainterQubits/Unitful.jl/issues/412).
