Inductance Converters
Convert between inductance units used in coils, transformers, power electronics, and circuit design. This hub applies exact SI henry scaling so prefix-based conversions remain consistent and reversible.
Explanation
Inductance describes how strongly a circuit opposes changes in current by storing energy in a magnetic field. The SI unit is the henry (H), defined as 1 H = 1 V·s/A. Prefix relationships are exact: 1 mH = 10⁻³ H, 1 µH = 10⁻⁶ H, and 1 kH = 10³ H. All conversions in this hub are purely multiplicative with no offsets. Every factor is derived by reducing units to henry and then applying exact SI prefix scaling. For clarity, inductance conversions are grouped into base-to-prefix and prefix-to-prefix relationships.
Frequently Asked Questions
What is inductance?
Inductance is the property of a circuit element that resists changes in current by storing energy in a magnetic field.
What is the SI unit of inductance?
The SI unit is the henry (H).
What does 1 henry represent?
One henry corresponds to 1 volt-second per ampere (1 H = 1 V·s/A).
How do microhenry and millihenry relate?
Both are decimal SI prefixes: 1 mH = 1000 µH, and 1 µH = 10⁻⁶ H.
Why are small inductance values common in electronics?
Many electronic components and switching circuits use small coils, so values are often expressed in µH or mH.
Are inductance conversions multiplicative?
Yes. SI prefix conversions are purely multiplicative with no additive offsets.
