Unit c℧
Name centimho
Category Electrical Conductance
Details In the field of electrical conductance, the centimho (c℧) is a unit used to measure the conductance of a material or a component. Conductance is the ability of a material or component to conduct electrical current. It is the reciprocal of resistance, so larger conductance represents lower resistance and better ability to conduct electric current.

The term centimho comes from "centi-" prefix, meaning one hundredth (1/100) and "mho," which is an older term for the unit siemens (S) - the modern standard unit for electrical conductance in the International System of Units (SI). A mho represents the inverse of the ohm (Ω), the unit of electrical resistance.

Therefore, a centimho can be defined as one hundredth (1/100) of a mho or a siemens.

1 c℧ = 1/100 S = 0.01 S

The use of the centimho unit is now considered obsolete and has mostly been replaced by the siemens or other subunits such as millisiemens (mS) or microsiemens (µS) for measuring electrical conductance.
