Convert Femtovolt to Millivolt
Input the number of femtovolts you want to convert to millivolts.
How to Convert Femtovolts to Millivolts
The femtovolt and millivolt are both units of voltage. By definition, 1 millivolt equals exactly 1e21 femtovolts. This means to convert femtovolts to millivolts, you divide by 1e21.
Formula
Step-by-Step Example
Convert 5 fV to millivolts:
We need to convert femtovolts to millivolts
Since 1 mV = 1e21 fV, divide by 1e21
5 ÷ 1e21 = 5e-21
5 fV = 5e-21 mV

About These Units
Femtovolt (fV)
A femtovolt (fV) equals 10⁻¹⁵ volts. Theoretical limit of voltage measurement—quantum effects dominate. SQUID magnetometers approach femtovolt sensitivity. Single-electron effects in quantum dots produce femtovolt-scale signals. Beyond practical measurement for most applications.
Millivolt (mV)
A millivolt (mV) equals 0.001 volts. Common for sensor outputs: thermocouple 0-50 mV, strain gauge 2-3 mV/V, audio line level 200-775 mV RMS. ECG signals: 1-10 mV. Solar cell open-circuit: 500-700 mV per cell. Critical for instrumentation and signal processing.
