Convert megohms to petaohms by entering a value below.
How to Convert Megohms to Petaohms
The megohm and petaohm are both units of electrical resistance. By definition, 1 petaohm equals exactly 1000000000 megohms. This means to convert megohms to petaohms, you divide by 1000000000.
Formula
Step-by-Step Example
Convert 5 MΩ to petaohms:
We need to convert megohms to petaohms
Since 1 PΩ = 1000000000 MΩ, divide by 1000000000
5 ÷ 1000000000 = 5e-9
5 MΩ = 5e-9 PΩ

About These Units
Megohm (MΩ)
A megohm (MΩ) equals 1,000,000 ohms or 1,000 kilohms. Used for insulation resistance testing (should be >1 MΩ), high-impedance circuits, input resistance of oscilloscopes (1-10 MΩ), and anti-static resistors.
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.
