How the Millihenry to Microhenry Converter Works

The millihenry to microhenry converter multiplies any millihenry (mH) input by 1,000 to produce the microhenry (μH) output. A millihenry is 10⁻³ henrys and a microhenry is 10⁻⁶ henrys. The conversion factor is a fixed 1,000.

Inductance values in the millihenry and microhenry ranges are common in switching regulators (1–100 μH), audio crossover networks (0.1–10 mH), RF chokes, and EMI filter inductors. Converting between mH and μH is routine in circuit design and component selection.

Enter a millihenry value and see the microhenry result instantly. The converter is bidirectional.

Millihenry to Microhenry Formula

μH = mH × 1,000

The formula is: μH = mH × 1,000. The prefix ratio is 10⁻³ ÷ 10⁻⁶ = 10³ = 1,000.

Example: A 2.2 mH audio inductor = 2,200 μH. A 0.47 mH EMI choke = 470 μH. A 10 mH power filter = 10,000 μH.

Frequently Asked Questions

How many microhenrys are in 1 millihenry?

Exactly 1,000 microhenrys (μH) are in 1 millihenry (mH). The SI prefix difference between milli and micro is always 10³ = 1,000.

When should I use mH vs μH for inductor values?

Use μH for values below 1,000 μH (1 mH) — typical in switch-mode power supplies and RF circuits. Use mH for larger inductors like audio crossover coils and power-line filters.

What inductance range do switching regulators use?

Most switching regulators (buck, boost, buck-boost) use inductors in the 1 μH to 470 μH range (0.001 mH to 0.47 mH). The exact value depends on switching frequency, input/output voltage, and load current.

How do I convert microhenrys to millihenrys?

Divide by 1,000. For example, 4,700 μH ÷ 1,000 = 4.7 mH. This converter supports both directions.

What determines the inductance of a coil?

Inductance depends on the number of turns squared, the core material permeability, the cross-sectional area of the core, and the length of the coil. Ferrite cores increase inductance by 100–10,000× compared to air cores.
