About Converting Petaohms to Megaohms
Petaohm and Megaohm both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Petaohm is 1000000000000000 ohm units, and megaohm is 1000000 ohm units.
Formula
megaohms = petaohms × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 petaohm equals 1e+15 base units, and 1 megaohm equals 1000000 base units, so dividing one by the other gives the direct petaohm-to-megaohm factor of 1000000000.
Simple example
1 POhm × 1000000000 = 1,000,000,000 MOhm
1 petaohm = 1,000,000,000 megaohms.
Real-world example
120 POhm × 1000000000 = 120,000,000,000 MOhm
120 petaohms = 120,000,000,000 megaohms.

Frequently asked questions
How many megaohms are in 1 petaohm?
1 petaohm equals 1,000,000,000 megaohms, using the exact defined conversion factor rather than an estimate.
How do I convert petaohm to megaohm?
Multiply the petaohm value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert megaohm back to petaohm?
Use the reverse factor: 1 megaohm equals 1e-9 petaohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a petaohm?
Petaohm (POhm) is a unit of electricity.
What is a megaohm?
Megaohm (MOhm) is a unit of electricity.
Is the petaohm to megaohm conversion exact?
Yes. Both petaohm and megaohm are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
