1. Convert to base units
S/m = input value x input unit factor
Every supported conductivity unit is stored as a factor relative to siemens per meter.

Common conversions
Useful conductivity conversion factors
| Conversion | Factor | Typical use |
|---|---|---|
| mS/cm to S/m | S/m = mS/cm x 0.1 | Water quality and lab data |
| uS/cm to S/m | S/m = uS/cm x 0.0001 | Low-conductivity fluids |
| S/m to mS/cm | mS/cm = S/m x 10 | Lab reports and instruments |
| S/cm to S/m | S/m = S/cm x 100 | Highly conductive materials |
| mS/m to S/m | S/m = mS/m / 1000 | Material and fluid data cleanup |
| MS/m to S/m | S/m = MS/m x 1,000,000 | Metals and high-conductivity materials |
How it works
Conductivity conversion method
2. Convert to target units
target value = base value / target unit factor
The selected result and table values are calculated from the same base value.
3. Check precision
rounding depends on scale
Very small and very large values use compact scientific notation to stay readable.
FAQ
