How the formula works
Both megaohm and petaohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megaohms by 1.000000e-09 to get petaohms. To reverse the conversion, multiply a petaohm value by 1.000000e+09 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 Petaohm (PΩ)?
A Petaohm (PΩ) equals 1e+15 ohm(s), a scaled unit of electrical resistance used for peta-scale electrical work.
How do I convert megaohms to petaohms?
Multiply the megaohm value by 1.000000e-09 to get the equivalent in petaohms. For example, 5 MΩ × 1.000000e-09 = 5.000000e-09 PΩ.
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 petaohms back to megaohms?
Yes. Divide the petaohm value by 1.000000e-09, or multiply it by 1.000000e+09, to get megaohms.
