Convert electrical units by family and calculate voltage, current, resistance, power, and energy with context values.
Context values
Some unit families need one extra value for a physically accurate result.
Femtovolt is 1e-15 volt units.
Result = input x 1e-6 / 1e-15.

About Converting Microvolts to Femtovolts
Microvolt 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: Microvolt is 0.000001 volt units, and femtovolt is 1e-15 volt units.
Formula
femtovolts = microvolts × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 microvolt equals 0.000001 base units, and 1 femtovolt equals 1e-15 base units, so dividing one by the other gives the direct microvolt-to-femtovolt factor of 1000000000.
Simple example
1 uV × 1000000000 = 1,000,000,000 fV
1 microvolt = 1,000,000,000 femtovolts.
Real-world example
120 uV × 1000000000 = 120,000,000,000 fV
120 microvolts = 120,000,000,000 femtovolts.

Reverse conversion: Femtovolt to Microvolt
1 fV × 1e-9 = 1e-9 uV
1 femtovolt = 1e-9 microvolts.
microvolts = femtovolts × 1e-9

Frequently asked questions
How many femtovolts are in 1 microvolt?
1 microvolt equals 1,000,000,000 femtovolts, using the exact defined conversion factor rather than an estimate.
How do I convert microvolt to femtovolt?
Multiply the microvolt value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert femtovolt back to microvolt?
Use the reverse factor: 1 femtovolt equals 1e-9 microvolts. You can also use the swap control in the converter above to flip the direction instantly.
What is a microvolt?
Microvolt (uV) is a unit of electricity.
What is a femtovolt?
Femtovolt (fV) is a unit of electricity.
Is the microvolt to femtovolt conversion exact?
Yes. Both microvolt and femtovolt are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 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.
