About Converting Yoctoohms to Attoohms
Yoctoohm and Attoohm 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: Yoctoohm is 1e-24 ohm units, and attoohm is 1e-18 ohm units.
Formula
attoohms = yoctoohms × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 yoctoohm equals 1e-24 base units, and 1 attoohm equals 1e-18 base units, so dividing one by the other gives the direct yoctoohm-to-attoohm factor of 0.000001.
Simple example
1 yOhm × 0.000001 = 0.000001 aOhm
1 yoctoohm = 0.000001 attoohms.
Real-world example
120 yOhm × 0.000001 = 0.00012 aOhm
120 yoctoohms = 0.00012 attoohms.

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