How the formula works
Both gigaohm and ohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigaohms by 1.000000e+09 to get ohms. To reverse the conversion, multiply a ohm value by 1.000000e-09 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 Ohm (Ω)?
The ohm (Ω) is the SI unit of electrical resistance, describing how strongly a material opposes current flow.
How do I convert gigaohms to ohms?
Multiply the gigaohm value by 1.000000e+09 to get the equivalent in ohms. For example, 5 GΩ × 1.000000e+09 = 5.000000e+09 Ω.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+09 is an exact, non-rounded value.
Can I convert ohms back to gigaohms?
Yes. Divide the ohm value by 1.000000e+09, or multiply it by 1.000000e-09, to get gigaohms.
