How to read your Electric Conductivity result

Electrical conductivity is a material property, the reciprocal of resistivity. The SI unit is siemens per metre. One dS/m equals 1 S/m, one mS/cm equals 0.1 S/m, and one µS/cm equals 1×10⁻⁴ S/m, which is the common unit for water quality.

Common mistakes when calculating Electric Conductivity

  • Mixing mS/cm and S/m, which differ by 10.
  • Confusing conductivity (S/m) with conductance (S).
  • Quoting water conductivity without temperature, since it rises with warmth.

Electric Conductivity FAQ

How many S/m is 1 mS/cm?

1 mS/cm is 0.1 S/m.

Is dS/m the same as S/m?

Yes. 1 dS/m equals exactly 1 S/m.

How many µS/cm is 1 mS/cm?

1 mS/cm is 1,000 µS/cm.

What is the base unit for electric conductivity?

This converter uses siemens per meter (S/m) as the common base unit: every value is first converted to it and then to the target unit.

How do I convert between two electric conductivity units?

Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.

How many millisiemens per centimeter are in 1 siemens per meter?

1 S/m = 10 mS/cm.

How many microsiemens per centimeter are in 1 siemens per meter?

1 S/m = 10,000 µS/cm.

How many decisiemens per meter are in 1 siemens per meter?

1 S/m = 10 dS/m.

Which electric conductivity units does this converter support?

It covers 7 units: siemens per meter (S/m), siemens per centimeter (S/cm), millisiemens per centimeter (mS/cm), microsiemens per centimeter (µS/cm), decisiemens per meter (dS/m), millisiemens per meter (mS/m), mho per meter (℧/m).

How accurate is the electric conductivity converter?

Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
