Fundamental Formulas for Millihenries to Microhenries Conversion
Converting millihenries (mH) to microhenries (µH) involves understanding the relationship between these units of inductance. Both are subunits of the henry (H), the SI unit of inductance.
- 1 henry (H) = 1,000 millihenries (mH)
- 1 millihenry (mH) = 1,000 microhenries (µH)
The primary formula for conversion is straightforward:
Where:
- Millihenries (mH): The inductance value in millihenries.
- Microhenries (µH): The inductance value in microhenries.
For reverse conversion:
This formula is essential for engineers and technicians working with inductors, transformers, and other electromagnetic components where precise inductance values are critical.
Additional Related Formulas
In some cases, inductance values are used in calculations involving frequency, reactance, and impedance. Here are some relevant formulas:
- Inductive Reactance (XL):XL = 2πfL
Where:
- XL = Inductive reactance (ohms, Ω)
- f = Frequency (hertz, Hz)
- L = Inductance (henries, H)
- Energy Stored in an Inductor (E):E = ½ L I²
Where:
- E = Energy (joules, J)
- L = Inductance (henries, H)
- I = Current (amperes, A)
Note that when using these formulas, inductance must be converted to henries (H). For example, if you have 5 mH, convert it to henries by dividing by 1000:

Expanded Technical Insights on Inductance Unit Conversions
Inductance units span a wide range, from picohenries (pH) to henries (H), reflecting the diverse applications in electronics and electromagnetics. The millihenry and microhenry units are particularly common in practical engineering due to their convenient scale for most inductors.
Millihenries (mH) are often used in power electronics, audio equipment, and sensor design, where inductance values typically range from a fraction of a millihenry to several tens of millihenries. Microhenries (µH), being 1000 times smaller, are prevalent in RF circuits, small signal inductors, and high-frequency applications.
Accurate conversion between these units is vital for:
- Component specification and procurement
- Simulation and modeling of circuits
- Ensuring compatibility between datasheets and design requirements
- Calculating related electrical parameters such as reactance and energy storage
Modern design tools and calculators, including AI-powered solutions, facilitate these conversions, reducing human error and improving design efficiency.
