What does a femtofarad represent?

A femtofarad (fF) is 10⁻¹⁵ farads and measures very small electrostatic capacitances in electronic devices and systems.

When is an exafarad used?

An exafarad (EF) equals 10¹⁸ farads and is used only for extremely large or theoretical capacitances such as planetary or astrophysical scales.

Why convert from femtofarads to exafarads?

This conversion helps compare capacitances across vastly different scales, from microelectronic devices to astronomical systems.
