How the formula works
Both megaohm and gigaohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megaohms by 0.001 to get gigaohms. To reverse the conversion, multiply a gigaohm value by 1000 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 Gigaohm (GΩ)?
A Gigaohm (GΩ) equals 1e+9 ohm(s), a scaled unit of electrical resistance used for giga-scale electrical work.
How do I convert megaohms to gigaohms?
Multiply the megaohm value by 0.001 to get the equivalent in gigaohms. For example, 5 MΩ × 0.001 = 0.005 GΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert gigaohms back to megaohms?
Yes. Divide the gigaohm value by 0.001, or multiply it by 1000, to get megaohms.
