About Converting Teraohms to Petaohms
Teraohm and Petaohm 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: Teraohm is 1000000000000 ohm units, and petaohm is 1000000000000000 ohm units.
Formula
petaohms = teraohms × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 teraohm equals 1e+12 base units, and 1 petaohm equals 1e+15 base units, so dividing one by the other gives the direct teraohm-to-petaohm factor of 0.001.
Simple example
1 TOhm × 0.001 = 0.001 POhm
1 teraohm = 0.001 petaohms.
Real-world example
120 TOhm × 0.001 = 0.12 POhm
120 teraohms = 0.12 petaohms.

Reverse conversion: Petaohm to Teraohm
0.001 POhm × 1000 = 1 TOhm
0.001 petaohms = 1 teraohm.
teraohms = petaohms × 1000

Frequently asked questions
How many petaohms are in 1 teraohm?
1 teraohm equals 0.001 petaohms, using the exact defined conversion factor rather than an estimate.
How do I convert teraohm to petaohm?
Multiply the teraohm value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert petaohm back to teraohm?
Use the reverse factor: 1 petaohm equals 1,000 teraohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a teraohm?
Teraohm (TOhm) is a unit of electricity.
What is a petaohm?
Petaohm (POhm) is a unit of electricity.
Is the teraohm to petaohm conversion exact?
Yes. Both teraohm and petaohm are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
