About Converting Picoohms to Rontoohms
Picoohm and Rontoohm 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: Picoohm is 1e-12 ohm units, and rontoohm is 1e-27 ohm units.
Formula
rontoohms = picoohms × 1e+15
This factor comes from each unit's defined relationship to the category's base unit: 1 picoohm equals 1e-12 base units, and 1 rontoohm equals 1e-27 base units, so dividing one by the other gives the direct picoohm-to-rontoohm factor of 1e+15.
Simple example
1 pOhm × 1e+15 = 1e+15 rOhm
1 picoohm = 1e+15 rontoohms.
Real-world example
120 pOhm × 1e+15 = 1.2e+17 rOhm
120 picoohms = 1.2e+17 rontoohms.

Frequently asked questions
How many rontoohms are in 1 picoohm?
1 picoohm equals 1e+15 rontoohms, using the exact defined conversion factor rather than an estimate.
How do I convert picoohm to rontoohm?
Multiply the picoohm value by 1e+15. The converter above does this instantly to whatever precision you set.
How do I convert rontoohm back to picoohm?
Use the reverse factor: 1 rontoohm equals 1e-15 picoohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a picoohm?
Picoohm (pOhm) is a unit of electricity.
What is a rontoohm?
Rontoohm (rOhm) is a unit of electricity.
Is the picoohm to rontoohm conversion exact?
Yes. Both picoohm and rontoohm are defined by fixed standards rather than physical artifacts, so the factor of 1e+15 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.
