How the formula works
Both petaohm and milliohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petaohms by 1.000000e+18 to get milliohms. To reverse the conversion, multiply a milliohm value by 1.000000e-18 to get back to petaohms.
Frequently asked questions
What is Petaohm (PΩ)?
A Petaohm (PΩ) equals 1e+15 ohm(s), a scaled unit of electrical resistance used for peta-scale electrical work.
What is Milliohm (mΩ)?
A Milliohm (mΩ) equals 1/1,000 ohm(s), a scaled unit of electrical resistance used for milli-scale electrical work.
How do I convert petaohms to milliohms?
Multiply the petaohm value by 1.000000e+18 to get the equivalent in milliohms. For example, 5 PΩ × 1.000000e+18 = 5.000000e+18 mΩ.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+18 is an exact, non-rounded value.
Can I convert milliohms back to petaohms?
Yes. Divide the milliohm value by 1.000000e+18, or multiply it by 1.000000e-18, to get petaohms.
