Siemens per Metre to Megasiemens per Metre (S/m to MS/m)
1 siemens per metre (S/m) = 0.000001 megasiemens per metre (MS/m). 1 MS/m = 1000000 S/m. Example: 15 S/m = 15 × 0.000001 = 0.000015 MS/m.

How to Convert Siemens per Metre to Megasiemens per Metre
- 1 S/m = 0.000001 MS/m
- 1 MS/m = 1000000 S/m
- Example: convert 15 S/m to MS/m: 15 S/m = 15 × 0.000001 MS/m = 0.000015 MS/m
Formula
MS/m = S/m ÷ 1000000
Derivation from SI units:
- The SI unit of electrical conductivity σ = 1/ρ
- 1 MS/m = 10⁶ S/m = 1 m/(Ω·mm²)
Both units are defined exactly, so the factor is exact. Siemens per Metre definition: siemens per metre; Megasiemens per Metre definition: megasiemens per metre.
Worked examples
- A reading of 0.5 S/m converts to 5 × 10⁻⁷ MS/m.
0.5 S/m × 0.000001 = 5 × 10⁻⁷ MS/m - A value of 1000000 S/m is 1 MS/m.
1000000 S/m × 0.000001 = 1 MS/m

Frequently asked questions
How many megasiemens per metre are in 1 siemens per metre?
1 S/m = 0.000001 MS/m.
How do I convert siemens per metre to megasiemens per metre?
Multiply the value in S/m by 0.000001, or divide it by 1000000. For example, 15 S/m × 0.000001 = 0.000015 MS/m.
Is the S/m to MS/m conversion exact?
Yes. Both units are defined exactly, and 1 S/m is exactly 0.000001 MS/m.
