About Inductance Converter
A comprehensive inductance converter tool that allows you to convert between various electrical inductance units. Whether you're working with inductors, transformers, or electrical engineering projects, this tool provides accurate conversions between henries, millihenries, microhenries, nanohenries, picohenries, kilohenries, and megahenries.
Why use a Inductance Converter?
Inductance conversion is essential in electronics and electrical engineering. Different components and applications use different scales of inductance units, from nanohenries in RF circuits to henries in power transformers. This tool eliminates calculation errors and saves time when working with inductor values, circuit analysis, or component selection.
Who is it for?
This tool is perfect for electrical engineers, electronics technicians, circuit designers, students studying electrical engineering, hobbyist electronics enthusiasts, and anyone working with inductors or electrical circuits that need accurate inductance unit conversions.

Frequently Asked Questions
How do I convert inductance units?
Enter the source value, pick the 'from' and 'to' units, and click Convert to see the result. Supports H (henry, SI), mH, μH, nH, pH, kH, MH, plus the CGS abhenry (abH) and stathenry (statH). Copy the converted value to clipboard. Conversion runs entirely in your browser — values never leave the device. Results are shown to up to 12 significant digits with trailing zeros removed; there is no precision setting.
What inductance units does this converter support?
H (henry, SI), mH, μH, nH, pH, kH, MH, plus the CGS units abhenry (abH = 10⁻⁹ H) and stathenry (statH ≈ 8.98755×10¹¹ H, from c² × 10⁻⁵ with c = 299,792,458 m/s). The set covers SI base and derived units, CGS electromagnetic and electrostatic units, and domain-specific units where relevant. SI prefixes (k, M, G, m, μ, n) apply where applicable. For any unit not in the list that you need converted, mention it via feedback — the unit set evolves based on user requests.
How accurate is the inductance conversion?
Conversions use the internationally-defined factors where they exist; the result is rounded to 12 significant digits for display. H is dimensionally weber per ampere (magnetic flux per current). Inductors store energy in magnetic field: E = ½LI². Modern SI definition tied to the elementary charge and Planck constant. Output is rounded to 12 significant digits for display, and there is no setting to change that.
What's the formula to convert microhenries (μH) to millihenries (mH)?
mH = μH ÷ 1,000. RF / wireless design (nH inductors for impedance matching), switching power supplies (μH/mH for energy storage), audio crossovers (mH for speaker filters), transformer specifications. For other inductance-unit pairs, the tool applies the appropriate exact conversion factor automatically — no manual formula needed. Results are rounded to 12 significant digits, which is more than engineering specs typically need.
What's the key accuracy caveat for inductance conversion?
**Inductance is measured in henries (H)** — the SI unit, named after Joseph Henry. Practical inductors span nH (RF inductors, antenna design) to H (large transformers, power supplies). **Inductors oppose changes in current**, the dual of capacitors which oppose changes in voltage. Used heavily in RF design, switching power supplies, and filters.
What's a common real-world use case for inductance conversion?
RF / wireless design (nH inductors for impedance matching), switching power supplies (μH/mH for energy storage), audio crossovers (mH for speaker filters), transformer specifications.
What inductance units are commonly confused?
**H vs mH vs μH vs nH** — standard SI prefixes. **'Inductance' vs 'mutual inductance'** — self-inductance is the property of one coil; mutual inductance is the coupling between two coils. **Inductive reactance** (impedance in AC circuits) = 2πfL (ohms).
How do I handle very large or very small inductance values?
Use SI prefixes for clean scaling: kilo (10³), mega (10⁶), giga (10⁹), milli (10⁻³), micro (10⁻⁶), nano (10⁻⁹). For very large or very small results, the tool switches to exponent notation (e.g. 1.23e15) at 1e15 and above or below 1e-9. H is dimensionally weber per ampere (magnetic flux per current). Inductors store energy in magnetic field: E = ½LI². Modern SI definition tied to the elementary charge and Planck constant. For data interchange, copy the value; it is shown to 12 significant digits.
