• 1 S/m = 10^-2 S/cm = 10³ mS/m = 10⁶ µS/m (SI chain)
• 1 µS/cm = 100 µS/m = 10^-4 S/m (standard water-quality scale)
• 1 mS/cm = 100 mS/m = 0.1 S/m (seawater ≈ 50 mS/cm)
• 1 S/cm = 100 S/m (used in analytical chemistry conductivity cells)
• Copper: 59.6 MS/m = 5.96 × 10⁷ S/m (100% IACS basis = 58 MS/m)
• 1 GS/m = 10⁹ S/m (cryogenically cooled pure metal scale)
• 1 statS/cm ≈ 1.113 × 10^-10 S/m (CGS-Gaussian, exact: 10⁷/c² S/m)
• 1 abS/cm = 10¹¹ S/m (CGS-EMU, exact)
