Decisiemens per Metre to Siemens per Metre (dS/m to S/m)
1 decisiemens per metre (dS/m) = 0.1 siemens per metre (S/m). 1 S/m = 10 dS/m. Example: 15 dS/m = 15 × 0.1 = 1.5 S/m.

How to Convert Decisiemens per Metre to Siemens per Metre
- 1 dS/m = 0.1 S/m
- 1 S/m = 10 dS/m
- Example: convert 15 dS/m to S/m: 15 dS/m = 15 × 0.1 S/m = 1.5 S/m
Formula
S/m = dS/m ÷ 10
Derivation from SI units:
- 1 dS/m = 0.1 S/m = 1 mS/cm
- The SI unit of electrical conductivity σ = 1/ρ
Both units are defined exactly, so the factor is exact. Decisiemens per Metre definition: decisiemens per metre; Siemens per Metre definition: siemens per metre.
Worked examples
- A reading of 1 dS/m converts to 0.1 S/m.
1 dS/m × 0.1 = 0.1 S/m - A value of 4 dS/m is 0.4 S/m.
4 dS/m × 0.1 = 0.4 S/m

Frequently asked questions
How many siemens per metre are in 1 decisiemens per metre?
1 dS/m = 0.1 S/m.
How do I convert decisiemens per metre to siemens per metre?
Multiply the value in dS/m by 0.1, or divide it by 10. For example, 15 dS/m × 0.1 = 1.5 S/m.
Is the dS/m to S/m conversion exact?
Yes. Both units are defined exactly, and 1 dS/m is exactly 0.1 S/m.
