Full name: megaohm
Plural form: megaohms
Symbol: MΩ
Alternate spelling: megohms
Category type: electric resistance
Scale factor: 1000000
The SI derived unit for electric resistance is the ohm.
1 ohm is equal to 1.0E-6 megaohm.
Valid units must be of the electric resistance type.
You can use this form to select from known units:
The SI prefix "mega" represents a factor of 106, or in exponential notation, 1E6.
So 1 megaohm = 106 ohms.
The definition of a ohm is as follows:
The ohm (symbol: Ω) is the SI unit of electrical impedance or, in the direct current case, electrical resistance, named after Georg Ohm. It is defined as the resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere, the conductor not being the seat of any electromotive force.
