megaohm

Million resistance units

A megaohm is one million ohms, a unit of electrical resistance.

The prefix mega- multiplies the base unit by a factor of one million.

Megaohms typically measure very high resistances, as in insulation testing or specialized electronics: The multimeter reads in the megaohm range.
