Unit fV
Name femtovolt
Category Electric Potential
Details The femtovolt (fV) is a unit of electric potential, which is also known as voltage. It is a part of the International System of Units (SI) and is derived from the base unit of voltage, the volt (V). One femtovolt is equal to 10^-15 volts, or 0.000000000000001 volts.

In the field of electric potential, voltage measures the difference in electric potential energy between two points in a circuit or an electric field. The femtovolt, being such a small unit, is often used to measure very low voltages or potential differences, such as the ones encountered in nanotechnology, sensitive electronic circuits, and biological processes.
