mho Electr.|məʊ|
[Proposed by Sir W. Thomson (now Lord Kelvin): reversed spelling of ohm.]
The unit of conductivity, being the conductivity of a body whose resistance is one ohm.
1883Sir W. Thomson Pop. Lect. (1889) I. 130 Such an instrument at once gives conductivity, and you want a name (suppose you adopt mho) for the unit of conductivity, and call the instrument a mhometer..The number of mhos, or of millimhos will..measure the number of lamps in circuit. 1892Gloss. Electr. Terms 12 in Lightning 3 Mar. Supp., Mho. The mho is the conductivity of a column of mercury of a constant cross section of one square millimetre, and of a length of 106·3 centimetres at the temperature of melting ice. (Note.—The conductivity of a conductor is the reciprocal of its resistance.)
So mhometer |ˈmɒmɪtə(r)|, an instrument for measuring electrical conductivities.
