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.

How to convert
Exact conversion factors in both directions, plus a worked example.
1 MΩ = 1000000 Ω
1 Ω = 0.000001 MΩ
To convert megaohm to ohm, multiply by 1000000.
To convert ohm to megaohm, multiply by 0.000001.
Example: convert 10 MΩ to Ω
10 × 1000000 = 10000000 Ω
About these units
Short background on the units used in this conversion.
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.
Frequently asked questions
How many ohms are in one megaohm?
One megaohm equals 1,000,000 ohms. Multiply your megaohms value by 1,000,000 to convert to ohms.
What is the conversion formula?
Ω = MΩ × 1,000,000The reverse is
MΩ = Ω × 0.000001, using the same exact factors as this converter.Is this Megaohm to Ohm converter private?
