About Converting Yoctovolts to Femtovolts
Yoctovolt and Femtovolt 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 femtovolt is 1e-15 volt units.
Formula
femtovolts = yoctovolts × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 yoctovolt equals 1e-24 base units, and 1 femtovolt equals 1e-15 base units, so dividing one by the other gives the direct yoctovolt-to-femtovolt factor of 1e-9.
Simple example
1 yV × 1e-9 = 1e-9 fV
1 yoctovolt = 1e-9 femtovolts.
Real-world example
120 yV × 1e-9 = 1.2e-7 fV
120 yoctovolts = 1.2e-7 femtovolts.

Frequently asked questions
How many femtovolts are in 1 yoctovolt?
1 yoctovolt equals 1e-9 femtovolts, using the exact defined conversion factor rather than an estimate.
How do I convert yoctovolt to femtovolt?
Multiply the yoctovolt value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert femtovolt back to yoctovolt?
Use the reverse factor: 1 femtovolt equals 1,000,000,000 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 femtovolt?
Femtovolt (fV) is a unit of electricity.
Is the yoctovolt to femtovolt conversion exact?
Yes. Both yoctovolt and femtovolt are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 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.
