Convert Milliohm to Petaohm
Convert milliohms to petaohms by entering a value below.
How to Convert Milliohms to Petaohms
The milliohm and petaohm are both units of electrical resistance. By definition, 1 petaohm equals exactly 1e18 milliohms. This means to convert milliohms to petaohms, you divide by 1e18.
Formula
Step-by-Step Example
Convert 5 mΩ to petaohms:
We need to convert milliohms to petaohms
Since 1 PΩ = 1e18 mΩ, divide by 1e18
5 ÷ 1e18 = 5e-18
5 mΩ = 5e-18 PΩ

About These Units
Milliohm (mΩ)
A milliohm (mΩ) equals 0.001 ohms. Used for current sense resistors (1-100 mΩ), PCB trace resistance, wire resistance, battery internal resistance (5-50 mΩ), and contact resistance. Measurement requires 4-wire technique for accuracy.
Petaohm (PΩ)
A petaohm (PΩ) equals 10¹⁵ ohms. Theoretical scale for extreme insulators: fused quartz, Teflon, and ultrapure materials approach this range. Surface resistance of clean insulators in vacuum. Measurement at practical limits.
