## Inverse conductance quantum: quantum resistance

**inverseConductanceQuantum** is the reciprocal of the conductance quantum, a resistance scale used in mesoscopic physics. It relates fundamental constants to quantized electrical conductance.

## Use with units

Keep it as a resistance quantity and convert with [to()](https://calcul.io/function/to/index.md). The related [von Klitzing constant](https://calcul.io/constants/klitzing/index.md) is another quantum Hall resistance scale; [multiply()](https://calcul.io/function/multiply/index.md) combines quantities safely.

## Caveat

Do not treat it as a generic circuit resistance without noting the physical regime and definition used.
