Microsiemens per centimeter to millisiemens per centimeter
Type a value in µS/cm to get it in mS/cm instantly.
0.5mS/cm
That's about the same as tap water. That is roughly 250 ppm of dissolved solids.
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 µS/cm to mS/cm
To convert microsiemens per centimeter to millisiemens per centimeter, multiply by 0.001.
Example: 500 µS/cm × 0.001 = 0.5 mS/cm.
In the other direction, 1 mS/cm = 1,000 µS/cm.
