FAQ
What is the conversion factor from MΩ to Ω?
1 MΩ equals 1000000 Ω. To convert, multiply the value in mega-ohms by 1000000.
How do I convert 1 MΩ to Ω?
1 MΩ = 1.00000e+6 Ω. For any value, multiply by 1000000.
How do I convert Ω back to MΩ?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 Ω = 1e-6 MΩ.
When would I need to convert mega-ohm to ohm?
Resistance conversions between MΩ and Ω are used in electrical-network analysis, instrumentation (RTD/thermistor specification), grounding and bonding measurements, and electronics design. Ohms cover most circuit calculations; kΩ and MΩ appear in input-impedance specs, while milli-ohms cover bus-bar joints and shunt resistors.
Is the conversion exact?
Yes. Both MΩ and Ω are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
