I want Mathematica to format quantities to more decimal places than the default.
For example I have tried
NumberForm[
N[
UnitConvert[Quantity["PlanckLength"] , "Meters" ]
,6]
,{6, 6}]
This is unfortunately incorrect.
I also tried:
QuantityForm[UnitConvert[Quantity["PlanckLength"], "Meters" ], LongForm"]
but this produces an ugly representation:
I want it to produce an output like the first result (except correct to 6 decimal places).
From Wikipedia and other resources on the web it seems that this quantity is known to 6 decimal places (by default Mathematica truncates it to 4 decimal places.)
