Full name: petamho Plural form: petamhos Category type: electric
conductance Scale factor: 1.0E+15 The SI derived unit for
electric conductance is the siemens. 1 siemens is equal to
1.0E-15 petamho. Valid units must be of the electric conductance
type. You can use this form to select from known units: I'm
feeling lucky, show me some random units The SI prefix "peta"
represents a factor of 1015, or in exponential notation, 1E15.
So 1 petamho = 1015 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.
