Unit fS
Name femtosiemens
Category Electrical Conductance
Details The femtosiemens (fS) is a unit of electrical conductance in the International System of Units (SI). It is a derived unit that measures the ease with which an electric current can flow through a material or conductor. The base unit of electrical conductance in the SI system is the siemens (S). One femtosiemens is equal to 10^-15 siemens, or 0.000000000000001 siemens.

In the context of electrical conductance, a smaller unit like the femtosiemens is useful for representing very low conductance values, such as in semiconductor materials, biological membranes, or other situations where electric current flows with considerable resistance.
