The conductanceQuantum is a fundamental unit of electrical conductance that appears in mesoscopic and quantum transport.
It is related to elementaryCharge and planckConstant. Its reciprocal is the resistance quantum; distinguish conductance in siemens from resistance in ohms.
Enter conductanceQuantum on a calculator line to see its built-in value, or place the name inside a longer expression. Keep any displayed unit attached when converting or combining physical quantities, and check that every other value uses a compatible dimension.
