Siemens per Metre to Decisiemens per Metre (S/m to dS/m)
1 siemens per metre (S/m) = 10 decisiemens per metre (dS/m). 1 dS/m = 0.1 S/m. Example: 15 S/m = 15 × 10 = 150 dS/m.

How to Convert Siemens per Metre to Decisiemens per Metre
- 1 S/m = 10 dS/m
- 1 dS/m = 0.1 S/m
- Example: convert 15 S/m to dS/m: 15 S/m = 15 × 10 dS/m = 150 dS/m
Formula
dS/m = S/m × 10
Derivation from SI units:
- The SI unit of electrical conductivity σ = 1/ρ
- 1 dS/m = 0.1 S/m = 1 mS/cm
Both units are defined exactly, so the factor is exact. Siemens per Metre definition: siemens per metre; Decisiemens per Metre definition: decisiemens per metre.
Worked examples
- A reading of 0.5 S/m converts to 5 dS/m.
0.5 S/m × 10 = 5 dS/m - A value of 1000000 S/m is 10000000 dS/m.
1000000 S/m × 10 = 10000000 dS/m

Frequently asked questions
How many decisiemens per metre are in 1 siemens per metre?
1 S/m = 10 dS/m.
How do I convert siemens per metre to decisiemens per metre?
Multiply the value in S/m by 10. For example, 15 S/m × 10 = 150 dS/m.
Is the S/m to dS/m conversion exact?
Yes. Both units are defined exactly, and 1 S/m is exactly 10 dS/m.
