About Converting Femtoohms to Picoohms
Femtoohm 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: Femtoohm is 1e-15 ohm units, and picoohm is 1e-12 ohm units.
Formula
picoohms = femtoohms × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 femtoohm equals 1e-15 base units, and 1 picoohm equals 1e-12 base units, so dividing one by the other gives the direct femtoohm-to-picoohm factor of 0.001.
Simple example
1 fOhm × 0.001 = 0.001 pOhm
1 femtoohm = 0.001 picoohms.
Real-world example
120 fOhm × 0.001 = 0.12 pOhm
120 femtoohms = 0.12 picoohms.

Reverse conversion: Picoohm to Femtoohm
0.001 pOhm × 1000 = 1 fOhm
0.001 picoohms = 1 femtoohm.
femtoohms = picoohms × 1000

Frequently asked questions
How many picoohms are in 1 femtoohm?
1 femtoohm equals 0.001 picoohms, using the exact defined conversion factor rather than an estimate.
How do I convert femtoohm to picoohm?
Multiply the femtoohm value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert picoohm back to femtoohm?
Use the reverse factor: 1 picoohm equals 1,000 femtoohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a femtoohm?
Femtoohm (fOhm) is a unit of electricity.
What is a picoohm?
Picoohm (pOhm) is a unit of electricity.
Is the femtoohm to picoohm conversion exact?
Yes. Both femtoohm and picoohm 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.
