What Is This Tool?
This converter enables you to transform inductance measurements expressed in stathenry, a cgs-electrostatic unit, into petahenry, an SI-derived unit representing extremely large inductance values. It is especially useful for translating between older theoretical units and modern large-scale unit systems.

Common Use Cases
-
Converting inductance in older or theoretical scientific papers using the cgs system.
-
Scaling inductance values for astrophysical or planetary model calculations.
-
Translating between unit systems in plasma physics or theoretical electrodynamics.
-
Analyzing large-scale electromagnetic properties where SI prefixes are applied.
Tips & Best Practices
-
Verify the system of units used in your source to ensure correct conversion direction.
-
Use this converter mainly for theoretical or very large-scale inductance values.
-
Cross-check results when working across cgs and SI frameworks due to differing conventions.
-
Refer to provided examples to validate your conversion calculations.
Limitations
-
Petahenry units represent very large inductance values uncommon in everyday electronics.
-
Conversion is rarely applicable to practical, small-scale inductance measurements.
-
Differences between cgs and SI electromagnetic units may cause confusion if care is not taken.
-
Not suitable for precise engineering requirements without consideration of unit system contexts.
Frequently Asked Questions
-
What does one stathenry (stH) represent?
-
One 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.
-
What is a petahenry (PH) used for?
-
A petahenry is an SI-derived unit equal to 10^15 henry, used to express extremely large inductances in theoretical or large-scale electromagnetic calculations.
-
Why convert from stathenry to petahenry?
-
Converting from stathenry to petahenry helps translate inductance values from the cgs-Gaussian system into the large-scale SI-based unit for use in astrophysical or planetary-scale modeling.
