What Is This Tool?
This converter allows you to change inductance values from henry (H), the SI standard unit, into stathenry (stH), which belongs to the cgs-electrostatic system. It helps relate modern SI measurements with cgs-based units often used in theoretical physics and older literature.
How to Use This Tool?
-
Enter the inductance value in henry (H) to start.
-
Select 'henry' as the input unit and 'stathenry' as the output unit.
-
Click the convert button to obtain the equivalent value in stathenry (stH).
-
Review the results and use them for theoretical or practical applications.
Key Features
-
Converts inductance units between henry and stathenry accurately.
-
Supports understanding of both SI and cgs-Gaussian unit systems.
-
Includes practical examples for straightforward use.
-
Browser-based tool with easy-to-use interface.
Examples
-
Convert 1 henry to stathenry: 1 H equals approximately 1.11265002973 × 10⁻¹² stH.
-
Convert 5 henry to stathenry: 5 H equals roughly 5.56325014865 × 10⁻¹² stH.
Common Use Cases
-
Specifying inductance in coils and inductors used in power supply and filters design.
-
Analyzing transformer and motor windings in electrical machine development.
-
Converting inductance values for theoretical work in electrodynamics, plasma physics, and astrophysics.
-
Interpreting older scientific papers that use cgs (Gaussian/ESU) units.
-
Educational purposes showing relations between different electromagnetic unit systems.
Tips & Best Practices
-
Always verify input units before conversion to avoid errors.
-
Use this converter when comparing SI and cgs-based inductance measurements.
-
Handle very small converted values carefully due to the small scale of stathenry.
-
Use the tool to aid understanding of electromagnetic theory in different unit systems.
Limitations
-
The stathenry unit is uncommon in practical engineering because of its extremely small size relative to the henry.
-
Converted values in stathenry can be minutely small and may require attention during calculations.
-
Different unit systems require cautious interpretation to avoid confusion between SI and cgs measurements.
Frequently Asked Questions
-
What is the henry unit used for?
-
The henry (H) measures inductance in the SI system, defining the electromotive force generated by changes in current in circuits, and is essential for coil and circuit design.
-
Why convert henry to stathenry?
-
Converting henry to stathenry helps relate modern inductance values to those expressed in the cgs-Gaussian system, which is important in theoretical physics and in understanding older literature.
-
Are stathenry values practical for engineering?
-
Typically no; the stathenry is rarely used in practical engineering applications because of its very small magnitude compared to the henry.
Key Terminology
-
Henry [H]
-
The SI unit of inductance representing the electromotive force produced by a change of one ampere per second in current.
-
Stathenry [stH]
-
The cgs-electrostatic unit of inductance defined by an electromotive force of one statvolt per change of one statampere per second.
-
Inductance
-
A property of an electrical circuit by which a change in current induces an electromotive force.
