femtofarad

Capacitanceexact by definition

The femtofarad is 10⁻¹⁵ of a farad. It is the unit of integrated circuit design, where a DRAM storage cell holds roughly 25 fF, a logic gate presents a few, and the change a finger makes on a capacitive touch pad is a fraction of one. The factor is exact, being an SI prefix.
