Millisiemens per centimeter to siemens per meter
Type a value in mS/cm to get it in S/m instantly.
50S/m
That's 10× as conductive as seawater, while copper is 1,192,000× higher. That is roughly 250,000 ppm of dissolved solids.
Convert the other way: S/m to mS/cm
What it means
How conductive is that?
The TDS estimate uses the common 0.5 factor. Real meters use 0.5 to 0.7 depending on which salts dominate.
The math
How to convert mS/cm to S/m
To convert millisiemens per centimeter to siemens per meter, multiply by 0.1.
Example: 500 mS/cm × 0.1 = 50 S/m.
In the other direction, 1 S/m = 10 mS/cm.
