What Is This Tool?
This converter allows you to translate inductance values from abhenry, a historical unit from the centimetre–gram–second electromagnetic system, into dekahenry, a modern SI-derived unit commonly used to measure large inductances.
How to Use This Tool?
-
Enter the value of inductance in abhenry units
-
Select abhenry (abH) as the starting unit
-
Choose dekahenry (daH) as the target unit
-
Click convert to obtain the equivalent value in dekahenry
-
Use the result to update legacy measurements or design specifications
Key Features
-
Converts inductance units from abhenry (abH) to dekahenry (daH)
-
Uses a precise conversion factor based on defined electromagnetic relationships
-
Simplifies interpreting legacy data in modern SI units
-
Browser-based and easy to operate without installation
-
Supports users in electrical engineering, physics research, and education
Examples
-
5 abH converts to 5 × 1e-10 daH = 5e-10 daH
-
1 abH converts to 1 × 1e-10 daH = 1e-10 daH
Common Use Cases
-
Updating older scientific and engineering papers that use the cgs-emu system
-
Converting legacy experimental data for compatibility with SI units
-
Designing large-scale inductors and electromagnets measured in dekahenry while referencing older units
-
Electrical distribution systems and traction applications requiring high inductance values
-
Physics education and research involving unit system reconciliations
Tips & Best Practices
-
Verify unit selection before conversion to avoid errors
-
Understand that abhenry values are typically very small compared to dekahenry
-
Use this tool primarily for historical or theoretical contexts rather than routine engineering measurements
-
Cross-check converted values when working with very small inductance to ensure appropriate precision
-
Refer to legacy documentation to properly interpret abhenry-based inductance values
Limitations
-
Abhenry units are extremely small relative to dekahenry, making direct practical measurements uncommon
-
Conversion precision may be affected when handling very small inductance values due to scale differences
-
Primarily relevant for historical or theoretical data; limited use in contemporary engineering workflows
Frequently Asked Questions
-
What is the abhenry unit used for?
-
The abhenry is an older unit of inductance used in the cgs-emu system, mainly found in historical scientific literature and legacy electromagnetic measurements.
-
Why convert abhenry to dekahenry?
-
Conversion is needed to interpret values from older cgs-emu data within the modern SI system, making them compatible with current engineering and scientific standards.
-
Is the conversion between abhenry and dekahenry commonly used today?
-
It is mostly applied for theoretical, historical, or educational purposes rather than everyday industrial applications.
Key Terminology
-
Abhenry (abH)
-
A historical inductance unit in the cgs-emu system representing inductance linking one abweber per one abampere.
-
Dekahenry (daH)
-
An SI-derived inductance unit equal to 10 henry, used for measuring large inductance values.
-
Inductance
-
A measure of the magnetic flux linkage per unit current, indicating the ability of a conductor to induce voltage.
