julia> uconvert(u"Gpc"^15, 1.0 * u"Gpc"^18 * u"Mpc"^-3)
1.0000000000000002e9 Gpc^15

julia> uconvert(u"Gpc"^16, 1.0 * u"Gpc"^19 * u"Mpc"^-3)
Inf Gpc^16

Probably has to do with some internal conversion to SI units. Standard Unitful.js units seem to avoid this, so there should be a way to do the same and fix it:

julia> uconvert(u"Ym"^100, 1.0 * u"Ym"^101 * u"Zm"^-1)
1000.0 Ym^100
Nevermind, looks like this is a general issue in Unitful.js: PainterQubits/Unitful.jl#647. Not sure if anything can be done on the UnitfulAstro end?
