How the formula works
Both gigaohm and megaohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigaohms by 1000 to get megaohms. To reverse the conversion, multiply a megaohm value by 0.001 to get back to gigaohms.
Frequently asked questions
What is Gigaohm (GΩ)?
A Gigaohm (GΩ) equals 1e+9 ohm(s), a scaled unit of electrical resistance used for giga-scale electrical work.
What is Megaohm (MΩ)?
A Megaohm (MΩ) equals 1e+6 ohm(s), a scaled unit of electrical resistance used for mega-scale electrical work.
How do I convert gigaohms to megaohms?
Multiply the gigaohm value by 1000 to get the equivalent in megaohms. For example, 5 GΩ × 1000 = 5000 MΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert megaohms back to gigaohms?
Yes. Divide the megaohm value by 1000, or multiply it by 0.001, to get gigaohms.
