Electric Conductance Explained: The Inverse of Resistance

Electric conductance (represented by the symbol G) quantifies the ease with which electric current flows through an electrical conductor or component. It is mathematically defined as the reciprocal of electrical resistance: G = 1 / R = I / V. Where resistance opposes charge migration and dissipates power as heat, conductance represents current throughput capacity per applied volt.

• Siemens (S): The coherent SI derived unit of electrical conductance, named in honor of German electrical engineer and industrialist Ernst Werner von Siemens. One Siemens is defined as the conductance of a conductor in which a current of one ampere is produced by an electric potential difference of one volt (1 S = 1 A/V = 1 Ω⁻¹ = 1 kg⁻¹·m⁻²·s³·A²). In legacy English and American textbooks, this quantity was historically termed the “mho” (ohm spelled backward, symbol ℧).
• Millisiemens (mS) & Microsiemens (μS): Standard decimal submultiples of the Siemens (1 mS = 0.001 S and 1 μS = 0.000001 S). These units are universally utilized in semiconductor transistor transconductance ratings (g_m), aqueous solution purity analysis, hydroponics nutrient solution monitoring, and electrochemistry.

Key Formulas & Conversion Rules

Keep these exact physical conversion rules handy for circuit analysis and electrolytic testing:

• Siemens to Millisiemens: Multiply Siemens by 1,000 (mS = S × 1,000).
• Millisiemens to Siemens: Divide Millisiemens by 1,000 (S = mS / 1,000 = mS × 0.001).
• Millisiemens to Microsiemens: Multiply Millisiemens by 1,000 (μS = mS × 1,000).
• Microsiemens to Millisiemens: Divide Microsiemens by 1,000 (mS = μS / 1,000 = μS × 0.001).
• Siemens to Microsiemens: Multiply Siemens by 1,000,000 (μS = S × 1,000,000 = S × 10⁶).
• Microsiemens to Siemens: Divide Microsiemens by 1,000,000 (S = μS / 1,000,000 = μS × 10⁻⁶).
