What Is This Tool?
This converter helps transform inductance measurements from femtohenry (fH), an SI derived unit for very small inductances, to abhenry (abH), a cgs-emu electromagnetic unit used mainly in older scientific contexts. It supports engineers and researchers working across modern and historical unit systems.
How to Use This Tool?
-
Enter the inductance value in femtohenry you wish to convert.
-
Select femtohenry (fH) as the source unit and abhenry (abH) as the target unit.
-
Click the convert button to see the equivalent value in abhenry.
-
Interpret the converted result for applications involving both unit systems.
Key Features
-
Converts inductance values between femtohenry and abhenry units.
-
Based on established conversion rate: 1 fH equals 0.000001 abH.
-
Useful for microelectronics, RF engineering, and historical data analysis.
-
Supports understanding legacy unit systems alongside SI units.
-
Browser-based tool for quick and easy calculations.
Examples
-
5 femtohenry [fH] converts to 0.000005 abhenry [abH].
-
10 femtohenry [fH] converts to 0.000010 abhenry [abH].
Common Use Cases
-
Specifying parasitic inductance in high-frequency electronic components.
-
Translating microelectronic inductance values to cgs-emu units for compatibility.
-
Analyzing legacy scientific papers and older electrical instrumentation data.
-
Performing theoretical work in electromagnetic systems using the cgs-emu framework.
Tips & Best Practices
-
Ensure familiarity with both SI and cgs-emu unit systems when converting values.
-
Double-check values when handling extremely small inductances due to measurement sensitivity.
-
Use this tool for interpreting historical data or specifications rather than current designs.
-
Maintain consistency in units when conducting calculations involving both inductance units.
Limitations
-
The abhenry unit is largely outdated and replaced by the henry in modern systems.
-
Converting between these units requires understanding of the respective unit conventions.
-
Small inductance measurements in femtohenry require precise instruments to ensure accuracy.
-
This conversion is rarely necessary unless dealing with legacy or theoretical datasets.
Frequently Asked Questions
-
What does femtohenry measure?
-
Femtohenry is an SI unit of inductance equal to 10^-15 henry, used to express extremely small inductance values in microelectronics and high-frequency applications.
-
Why convert femtohenry to abhenry?
-
Converting femtohenry to abhenry helps interpret measurements between the modern SI system and older cgs-emu electromagnetic units, especially useful for legacy data and theoretical research.
-
Is abhenry commonly used today?
-
No, abhenry is mostly obsolete and replaced by the henry in SI units, but it remains relevant in contexts involving historical literature and cgs-emu based work.
Key Terminology
-
Femtohenry (fH)
-
An SI derived unit of inductance equal to 10^-15 henry, representing very small inductances in microelectronic and high-frequency applications.
-
Abhenry (abH)
-
A unit of inductance in the cgs-emu system, defined by the magnetic flux linkage of one abweber per abampere; historically used but largely replaced by the henry.
-
Inductance
-
A property of an electrical conductor that quantifies its ability to store magnetic energy when current flows through it.
