What Is This Tool?
This tool allows you to convert inductance values from femtohenry (fH), a unit for extremely small inductances, to decihenry (dH), a unit representing one tenth of a henry. It is useful for translating very small inductance measurements into larger, practical units commonly used in circuit design and engineering.

Care is needed when interpreting very small values in circuit models or designs
Frequently Asked Questions
-
What is a femtohenry used for?
-
Femtohenry is used to express extremely small inductance values in microelectronics, such as parasitic inductance in PCB traces and on-chip inductors.
-
Why convert femtohenry to decihenry?
-
Converting femtohenry to decihenry helps translate ultra-small inductance measurements into larger units used in practical circuit and filter design.
-
Are there limitations when converting between these units?
-
Yes, the conversion results often in very small decimal values due to the scale difference, which may be beyond practical measurement or significance in some contexts.
Key Terminology
-
Femtohenry [fH]
-
An SI derived unit of inductance equal to 10^-15 henry, used for very small inductance values in microelectronics.
-
Decihenry [dH]
-
An SI derived unit of inductance equal to one tenth of a henry (0.1 H) commonly used in medium-range inductors and filters.
-
Inductance
-
A measure of a conductor’s ability to store magnetic energy when current flows, influencing electromotive force in circuits.
