How to Convert Millihenries to Microhenries
The millihenry and microhenry are both units of inductance. By definition, 1 millihenry equals exactly 1e12 microhenries. This means to convert millihenries to microhenries, you multiply by 1e12.
Formula
Step-by-Step Example
Convert 5 mH to microhenries:
We need to convert millihenries to microhenries
Since 1 mH = 1e12 μH, multiply by 1e12
5 × 1e12 = 5e12
5 mH = 5e12 μH

About These Units
Millihenry (mH)
A millihenry (mH) equals 0.001 henries or 1,000 microhenries. Common for power inductors (1-100 mH), audio crossover coils (0.1-10 mH), EMI filter chokes, and relay coils. Speaker crossover inductors typically range from 0.5-5 mH.
Microhenry (μH)
A microhenry (μH) equals 10⁻⁶ henries or 1,000 nanohenries. Standard for RF inductors (0.1-1000 μH), switching power supply inductors (1-100 μH), and DC-DC converter chokes. AM radio tuning coils: 200-300 μH. Also written as uH.
