How the formula works
Both ohm and gigaohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ohms by 1.000000e-09 to get gigaohms. To reverse the conversion, multiply a gigaohm value by 1.000000e+09 to get back to ohms.
Frequently asked questions
What is Ohm (Ω)?
The ohm (Ω) is the SI unit of electrical resistance, describing how strongly a material opposes current flow.
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 ohms to gigaohms?
Multiply the ohm value by 1.000000e-09 to get the equivalent in gigaohms. For example, 5 Ω × 1.000000e-09 = 5.000000e-09 GΩ.
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 gigaohms back to ohms?
Yes. Divide the gigaohm value by 1.000000e-09, or multiply it by 1.000000e+09, to get ohms.
