-
Supports scientific and theoretical applications using different unit systems.
-
Offers a browser-based, easy-to-use interface for quick conversions.
Examples
-
Convert 2 hH to stathenry: 2 hH equals 2 × 1.11265002973e-10 stH = 2.22530005946e-10 stH.
-
Convert 0.5 hH to stathenry: 0.5 hH equals 0.5 × 1.11265002973e-10 stH = 5.56325014865e-11 stH.
Common Use Cases
-
Expressing very large inductances in power reactors and high-energy coils.
-
Translating inductance data between modern metric and cgs (Gaussian/ESU) unit systems.
-
Performing theoretical calculations in electrodynamics, plasma physics, or astrophysics.
-
Understanding inductance in older publications or pedagogical electromagnetic frameworks.
Tips & Best Practices
-
Verify unit system consistency when converting between hectohenry and stathenry.
-
Handle very small converted values with attention to numerical precision.
-
Use this converter mainly for theoretical, research, or educational purposes rather than practical engineering.
-
Refer to original unit definitions to ensure correct physical interpretation after conversion.
Limitations
-
Converted values in stathenry can be extremely small due to the unit size difference.
-
This conversion is primarily applicable in theoretical or historical contexts.
-
Practical engineering generally relies on SI units like henries instead of stathenry.
-
Care is needed to maintain dimensional consistency and correct interpretation across unit systems.
Frequently Asked Questions
-
What is a hectohenry used for?
-
A hectohenry is a metric unit of inductance used to describe very large inductances in applications such as power-system reactors and high-energy coils.
-
Why convert hectohenry to stathenry?
-
Conversion to stathenry is useful to interpret inductance values in older or theoretical works that use the cgs (Gaussian/ESU) unit system.
-
Are stathenry units common in practical engineering?
-
No, stathenry is mostly used in theoretical, pedagogical, or historical contexts; practical engineering prefers SI units like henries.
Key Terminology
-
Hectohenry (hH)
-
A metric unit of electrical inductance equal to 100 henries, used for expressing large inductance values.
-
Stathenry (stH)
-
A cgs-electrostatic unit of inductance where 1 stH induces 1 statvolt of electromotive force when current changes at 1 statampere per second.
-
Inductance
-
A measure of a circuit element's ability to store magnetic energy per unit current.
