1. Plural of abmho; a unit of electrical conductance equal to one billionth of a mho (or one nanosiemens).
Usage: technical; physics; rarely used in modern practice; siemens is the standard SI unit

Examples

• The conductance of the circuit was measured in abmhos.
• Early electrical engineers sometimes expressed small conductances in abmhos.
• One abmho equals 10⁻⁹ siemens.
