## What Is a Siemens?

A siemens is a unit used to measure electrical conductance.

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.

### Background and Origin

The siemens is named in honor of inventor Ernst Werner von Siemens, who played a pivotal role in the creation of the telegraph industry. Some challenge that the unit is named for his brother Sir William Siemens.[1]

## How Much Is a Siemens?

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.

## How to Convert Siemens

To convert siemens to another unit of electrical conductance, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[2]

You can find the conversion factors for siemens in the conversion table below.

Then, multiply the electrical conductance measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

siemens × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
