Convert Millihenry to Picohenry
Input the number of millihenries you want to convert to picohenries.
How to Convert Millihenries to Picohenries
The millihenry and picohenry are both units of inductance. By definition, 1 millihenry equals exactly 1e18 picohenries. This means to convert millihenries to picohenries, you multiply by 1e18.
Formula
Step-by-Step Example
Convert 5 mH to picohenries:
We need to convert millihenries to picohenries
Since 1 mH = 1e18 pH, multiply by 1e18
5 × 1e18 = 5e18
5 mH = 5e18 pH

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.
Picohenry (pH)
A picohenry (pH) equals 10⁻¹² henries. Measures parasitic inductance in PCB traces (10-100 pH/mm), bond wires (1-5 nH), IC packages, and high-speed digital circuits. Via hole inductance: 0.5-1 nH. Critical for GHz-frequency design.
