Ohm (Ω)
The ohm (Ω) is the SI unit of electrical resistance — one volt per ampere (V/A), the inverse of siemens.
Ohms quantify resistors, wire resistance, input impedance, and any opposition to current flow in circuits.

How to convert
Exact conversion factors in both directions, plus a worked example.
1 Ω = 0.000001 MΩ
1 MΩ = 1000000 Ω
To convert ohm to megaohm, multiply by 0.000001.
To convert megaohm to ohm, multiply by 1000000.
Example: convert 10 Ω to MΩ
10 × 0.000001 = 0.00001 MΩ
About these units
Short background on the units used in this conversion.
Megaohm (MΩ)
The megaohm (MΩ) equals one million ohms — used for high-value resistors, insulation resistance, and megger tests.
Megaohms appear on high-voltage insulation tests, MOSFET gate biasing, and leakage-path measurements.
Frequently asked questions
How many megaohms are in one ohm?
One ohm equals 0.000001 megaohms. Multiply your ohms value by 0.000001 to convert to megaohms.
What is the conversion formula?
MΩ = Ω × 0.000001The reverse is
Ω = MΩ × 1,000,000, using the same exact factors as this converter.Is this Ohm to Megaohm converter private?
