About Converting Yoctovolts to Attovolts
Yoctovolt and Attovolt 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: Yoctovolt is 1e-24 volt units, and attovolt is 1e-18 volt units.
Formula
attovolts = yoctovolts × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 yoctovolt equals 1e-24 base units, and 1 attovolt equals 1e-18 base units, so dividing one by the other gives the direct yoctovolt-to-attovolt factor of 0.000001.
Simple example
1 yV × 0.000001 = 0.000001 aV
1 yoctovolt = 0.000001 attovolts.
Real-world example
120 yV × 0.000001 = 0.00012 aV
120 yoctovolts = 0.00012 attovolts.

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