How to Convert Micromhos to Siemens

To convert a micromho measurement to a siemens measurement, divide the electrical conductance by the conversion ratio.

Since one siemens is equal to 1,000,000 micromhos, you can use this simple formula to convert:

siemens = micromhos ÷ 1,000,000

The electrical conductance in siemens is equal to the micromhos divided by 1,000,000.

For example, here's how to convert 500,000 micromhos to siemens using the formula above.
500,000 μ℧ = (500,000 ÷ 1,000,000) = 0.5 S

Micromhos and siemens are both units used to measure electrical conductance. Keep reading to learn more about each unit of measure.


The micromho is a unit of electrical conductance equal to 1/1,000,000 of a mho, which is the reciprocal of the resistance in ohms. One micromho is equal to one microsiemens.

In the metric system, "micro" is the prefix for 10-6. A micromho is sometimes also referred to as a gemmho. Micromhos can be abbreviated as μ℧; for example, 1 micromho can be written as 1 μ℧.


One siemens is the electrical conductance equal to an increase in current of one ampere for every increase in electrical potential difference of one volt. The siemens is the SI defined unit equal to the mho, and is the reciprocal of the resistance in ohms.

The siemens is the SI derived unit for electrical conductance in the metric system. Siemens can be abbreviated as S; for example, 1 siemens can be written as 1 S.
