You can do the reverse unit conversion from attomho to hectosiemens, or enter any two units below:

The SI prefix "hecto" represents a factor of
10^{2}, or in exponential notation, 1E2.

So 1 hectosiemens = 10^{2} siemens.

The definition of a siemens is as follows:

The siemens is the SI derived unit of electric conductance. It is equal to inverse ohm. It is named after the German inventor and industrialist Ernst Werner von Siemens, and was previously called the mho. In English, the term siemens is used both for the singular and plural. The 14th General Conference on Weights and Measures approved the addition of the siemens as an SI derived unit in 1971.

The SI prefix "atto" represents a factor of
10^{-18}, or in exponential notation, 1E-18.

So 1 attomho = 10^{-18} mhos.

The definition of a mho is as follows:

The SI derived unit of electric conductance is the siemens, which was previously referred to by the term mho. That term came from spelling ohm backwards and was written with an upside-down capital Greek letter Omega. The term siemens, as it is an SI unit, is used universally in science and primarily in electrical applications, while mho is still used primarily in electronic applications.
