original question: What's the unit of charge of [Planck units] system?
answer: planck charge
answer type: Unit of Charge.
auxiliary information: In physics, Planck units are physical units of measurement defined exclusively in terms of five universal physical constants listed below, in such a manner that these five physical constants take on the numerical value of 1 when expressed in terms of these units. Planck units have profound significance for theoretical physics since they elegantly simplify several recurring algebraic expressions of physical law by nondimensionalization. They are particularly relevant in research on unified theories such as quantum gravity.
in the [Planck units] system what is the unit of charge?
