About Converting Attoohms to Picoohms
Attoohm and Picoohm 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: Attoohm is 1e-18 ohm units, and picoohm is 1e-12 ohm units.
Formula
picoohms = attoohms × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 attoohm equals 1e-18 base units, and 1 picoohm equals 1e-12 base units, so dividing one by the other gives the direct attoohm-to-picoohm factor of 0.000001.
Simple example
1 aOhm × 0.000001 = 0.000001 pOhm
1 attoohm = 0.000001 picoohms.
Real-world example
120 aOhm × 0.000001 = 0.00012 pOhm
120 attoohms = 0.00012 picoohms.

Reverse conversion: Picoohm to Attoohm
0.000001 pOhm × 1000000 = 1 aOhm
0.000001 picoohms = 1 attoohms.
attoohms = picoohms × 1000000

Frequently asked questions
How many picoohms are in 1 attoohm?
1 attoohm equals 0.000001 picoohms, using the exact defined conversion factor rather than an estimate.
How do I convert attoohm to picoohm?
Multiply the attoohm value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert picoohm back to attoohm?
Use the reverse factor: 1 picoohm equals 1,000,000 attoohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a attoohm?
Attoohm (aOhm) is a unit of electricity.
What is a picoohm?
Picoohm (pOhm) is a unit of electricity.
Is the attoohm to picoohm conversion exact?
Yes. Both attoohm and picoohm are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
