The SI prefix "mega" represents a factor of
10^{6}, or in exponential notation, 1E6.

So 1 megaohm = 10^{6} 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.
