1. A unit of electrical conductance equal to one millionth of a mho, or one siemens.
Usage: technical; electronics; largely superseded by the siemens unit in modern usage

Examples

• The conductance of the resistor was measured in micromhos.
• Early semiconductor devices were characterized using micromho measurements.
• The circuit's conductance increased by several micromhos when the temperature rose.
• Engineers in the 1960s commonly used micromhos to specify component performance.
