Frequently Asked Questions
-
What is the stathenry unit used for?
-
The stathenry is the cgs-electrostatic unit of inductance used mainly in theoretical physics, plasma physics, and astrophysics contexts.
-
Why convert stathenry to femtohenry?
-
Converting to femtohenry allows expressing inductance in the SI system, especially useful for very small inductances relevant in microelectronics and high-frequency applications.
-
Is the stathenry commonly used in engineering?
-
No, stathenry is rarely used outside specialized theoretical contexts; most practical applications use SI units like the henry and femtohenry.
Key Terminology
-
Stathenry [stH]
-
A cgs-electrostatic (Gaussian/ESU) unit of inductance defined by the electromotive force produced when current changes at a rate of 1 statampere per second.
-
Femtohenry [fH]
-
An SI derived unit of inductance equal to 10^-15 henry, used to measure very small inductances in high-frequency and microelectronic applications.
-
Inductance
-
The property of a conductor by which a change in current induces an electromotive force.
