  4. Get Result: View the converted value instantly.

What This Calculator Measures

Inductance (L) is the property of an electrical conductor (usually a coil) that opposes changes in electric current. The standard SI unit is the Henry (H).

Formula or Logic

Inductance conversion is based on metric powers of 10:

  • 1 H = 1,000 mH (millihenry)
  • 1 mH = 1,000 µH (microhenry)
  • 1 µH = 1,000 nH (nanohenry)

Example Calculations

  • Example 1: Convert 470 µH to mH.
  • Calculation: 470 / 1000 = 0.47 mH.
  • Example 2: Convert 15 mH to H.
  • Calculation: 15 / 1000 = 0.015 H.

Understanding Your Results

Your result represents the same inductance level. Large units (H) are used for heavy transformers, while small units (µH, nH) are common in high-frequency RF circuits and small electronics.

Common Mistakes to Avoid

  • Milli vs Micro: Confusing mH and µH.
  • Component ID: Misreading inductor color codes or labels.
  • Rounding: Losing precision when designing sensitive filters or oscillators.

Frequently Asked Questions

Inductance is a coil's ability to resist changes in current by storing energy in a magnetic field.
Inductance is measured in henry (H). Smaller common units are millihenry (mH), microhenry (µH), and nanohenry (nH).
Divide by 1,000. For example, 470 µH becomes 0.47 mH.
Divide by 1,000. For example, 15 mH becomes 0.015 H.
Divide by 1,000. For example, 820 nH becomes 0.82 µH.
Most electronic inductors have small inductance values, so µH is a more convenient unit to read and compare.
No. Inductance is a component property. Impedance depends on frequency and includes resistance and reactance.
The inductance rating is usually treated as constant, but real components can behave differently at high frequency due to losses and parasitics.
"µ" means micro, which is one-millionth (10⁻⁶). So 1 µH = 0.000001 H.
nH is common in RF and high-speed circuits where inductance values are very small and precision matters.
