How the formula works
Both megaohm and ohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megaohms by 1.000000e+06 to get ohms. To reverse the conversion, multiply a ohm value by 0.000001 to get back to megaohms.
Frequently asked questions
What is Megaohm (MΩ)?
A Megaohm (MΩ) equals 1e+6 ohm(s), a scaled unit of electrical resistance used for mega-scale electrical work.
What is Ohm (Ω)?
The ohm (Ω) is the SI unit of electrical resistance, describing how strongly a material opposes current flow.
How do I convert megaohms to ohms?
Multiply the megaohm value by 1.000000e+06 to get the equivalent in ohms. For example, 5 MΩ × 1.000000e+06 = 5.000000e+06 Ω.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+06 is an exact, non-rounded value.
Can I convert ohms back to megaohms?
Yes. Divide the ohm value by 1.000000e+06, or multiply it by 0.000001, to get megaohms.
