Convert Milliohm to Reciprocal Siemens
Convert milliohms to reciprocal siemens by entering a value below.
How to Convert Milliohms to Reciprocal Siemens
The milliohm and reciprocal siemens are both units of electrical resistance. By definition, 1 reciprocal siemens equals exactly 1000 milliohms. This means to convert milliohms to reciprocal siemens, you divide by 1000.
Formula
Step-by-Step Example
Convert 5 mΩ to reciprocal siemens:
We need to convert milliohms to reciprocal siemens
Since 1 1/S = 1000 mΩ, divide by 1000
5 ÷ 1000 = 0.005
5 mΩ = 0.005 1/S

About These Units
Milliohm (mΩ)
A milliohm (mΩ) equals 0.001 ohms. Used for current sense resistors (1-100 mΩ), PCB trace resistance, wire resistance, battery internal resistance (5-50 mΩ), and contact resistance. Measurement requires 4-wire technique for accuracy.
Reciprocal Siemens (1/S)
The ohm is the reciprocal of the siemens (S), the unit of conductance. Resistance R = 1/G where G is conductance. A 1 kΩ resistor has conductance of 0.001 S = 1 mS. Siemens was formerly called "mho" (ohm spelled backward). R(Ω) = 1/G(S).
