Examples
-
2 stH is equal to 1.7975104 × 10²¹ EMU of inductance.
-
0.5 stH converts to 4.493776 × 10²⁰ EMU of inductance.
Common Use Cases
-
Interpreting inductance values from older or theoretical papers using the cgs‑electrostatic system.
-
Conducting analytical calculations in theoretical electrodynamics, plasma physics, or astrophysics with CGS units.
-
Converting historical electromagnetic data from CGS-ESU to CGS-EMU units for cross-system analysis.
-
Characterizing very small inductances in precision coil design or electromagnetic device prototyping.
Tips & Best Practices
-
Always verify the context of inductance values before converting, especially in historical texts.
-
Handle the large conversion factor carefully to avoid errors in numerical precision.
-
Use this conversion mainly for theoretical, historical, or specialized research involving CGS systems.
-
Confirm unit selections match the physical quantities under consideration to ensure meaningful results.
Limitations
-
The huge conversion factor reflects fundamentally different unit systems and scales, potentially causing confusion.
-
These units are mostly outdated and rarely applied in modern engineering, limiting practical usage.
-
High numerical scale can impact computational precision and demands attentive handling.
-
Conversions are mostly relevant for historical or theoretical electromagnetic research, not general engineering.
Frequently Asked Questions
-
What is a stathenry (stH)?
-
The stathenry is the cgs-electrostatic unit of inductance, defined so that an inductor of 1 stH produces an electromotive force of 1 statvolt when the current changes at 1 statampere per second.
-
How is the EMU of inductance defined?
-
The EMU of inductance, also known as the abhenry, is the unit in the cgs-electromagnetic system measuring magnetic flux linkage per unit current, equal to 10⁻⁹ henry in SI units.
-
Why convert between stathenry and EMU of inductance?
-
Converting between these units enables reinterpretation of inductance values between distinct CGS subsystems, facilitating cross-system comparison and analysis in theoretical and historical contexts.
-
Are these units commonly used today?
-
No, both stathenry and EMU of inductance are largely archaic, with SI units prevailing in modern engineering practice.
