What Is This Tool?
This tool allows you to convert inductance measurements from femtohenry, representing extremely small inductances, to exahenry, which denotes extremely large inductances. It facilitates comparisons, SI-prefix scaling, and unit conversions across very different orders of magnitude used in microelectronics and large-scale electromagnetic modeling.
How to Use This Tool?
-
Enter the inductance value in femtohenry [fH] you wish to convert
-
Select femtohenry as the source unit and exahenry as the target unit
-
Click the convert button to get the equivalent value in exahenry
-
Review the results and use them for comparisons or analysis
-
Refer to examples provided to better understand conversions
Key Features
-
Converts inductance values from femtohenry [fH] to exahenry [EH]
-
Uses official SI unit definitions for conversion
-
Provides examples to illustrate conversion results
-
Supports understanding of scale differences between units
-
Ideal for microelectronics and astrophysical modeling contexts
Examples
-
5 femtohenry [fH] converts to 5 × 1e-33 = 5e-33 exahenry [EH]
-
100 femtohenry [fH] converts to 100 × 1e-33 = 1e-31 exahenry [EH]
Common Use Cases
-
Specifying parasitic inductance for short PCB traces and component leads in high-frequency circuits
-
Characterizing on-chip inductors and MEMS devices in integrated circuit design
-
Modeling extremely large inductances in astrophysical or geophysical electromagnetic studies
-
Performing SI-prefix conversions and comparing inductance scales
-
Educational demonstrations of unit scales and the exa prefix
Tips & Best Practices
-
Check unit selection carefully to ensure proper conversion direction
-
Use this conversion primarily for educational or illustrative purposes due to scale differences
-
Refer to examples to validate conversion results
-
Understand the context of the units to apply values appropriately
-
Be aware that converted values can be extremely small decimal numbers
Limitations
-
Conversion results often yield extremely small decimal values that might be insignificant in practical applications
-
The exahenry unit is mainly theoretical and seldom used in typical electronics engineering
-
Conversions to exahenry are more academic or illustrative than for direct engineering use
-
Very large scale differences mean this tool is not intended for routine circuit design calculations
Frequently Asked Questions
-
What is the femtohenry unit used for?
-
Femtohenry is used to specify very small inductances found in microelectronics, such as parasitic inductance in PCB traces and component leads at RF and microwave frequencies.
-
Why convert femtohenry to exahenry?
-
This conversion helps compare extremely small inductances with vastly larger theoretical values used in astrophysical or geophysical electromagnetic models, aiding in understanding SI-prefix scaling.
-
Is the exahenry unit commonly used in electronics?
-
No, the exahenry is mostly theoretical and rarely applied in typical electronic contexts, being more relevant for large-scale electromagnetic phenomena or educational purposes.
Key Terminology

-
Exahenry [EH]
-
An SI unit of inductance equal to 10^18 henry, applied mainly in theoretical and large-scale electromagnetic contexts.
-
Inductance
-
A measure of a conductor's ability to store magnetic energy as magnetic flux linkage per unit of current.
