Context values
Some unit families need one extra value for a physically accurate result.
Microvolt is 0.000001 volt units.
Result = input x 1e-15 / 1e-6.

About Converting Femtovolts to Microvolts
Femtovolt and Microvolt 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: Femtovolt is 1e-15 volt units, and microvolt is 0.000001 volt units.
Formula
microvolts = femtovolts × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 femtovolt equals 1e-15 base units, and 1 microvolt equals 0.000001 base units, so dividing one by the other gives the direct femtovolt-to-microvolt factor of 1e-9.
Simple example
1 fV × 1e-9 = 1e-9 uV
1 femtovolt = 1e-9 microvolts.
Real-world example
120 fV × 1e-9 = 1.2e-7 uV
120 femtovolts = 1.2e-7 microvolts.

Reverse conversion: Microvolt to Femtovolt
1e-9 uV × 1000000000 = 1 fV
1e-9 microvolts = 1 femtovolt.
femtovolts = microvolts × 1000000000

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