Electric Conductance Converter
Conductance is the reciprocal of resistance: how easily current flows through a component. The SI unit is the siemens (S), historically called the mho.
1 Siemens = 1,000 Millisiemens
How to convert Siemens to Millisiemens
One Siemens equals 1,000 Millisiemens, so multiply any value in S by 1,000 to get mS. To convert back, divide by 1,000 — or multiply by 0.001.
mS = S × 1,000
Example: 25 S × 1,000 = 25,000 mS.
