Full name: attomho
Plural form: attomhos
Category type: electric conductance
Scale factor: 1.0E-18
The SI derived unit for electric conductance is the siemens.
1 siemens is equal to 1.0E+18 attomho.
Valid units must be of the electric conductance type.
You can use this form to select from known units:

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.
