Siemens per meter to millisiemens per centimeter
Type a value in S/m to get it in mS/cm instantly.
5,000mS/cm
That's 100× as conductive as seawater, while copper is 119,200× higher. That is roughly 2,500,000 ppm of dissolved solids.
Convert the other way: mS/cm to S/m
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 S/m to mS/cm
To convert siemens per meter to millisiemens per centimeter, multiply by 10.
Example: 500 S/m × 10 = 5,000 mS/cm.
In the other direction, 1 mS/cm = 0.1 S/m.
