How to Calculate Resistance to Conductance
Because conductance is the exact reciprocal of resistance, determining the conductance of any component or circuit requires a single division operation. Here is the primary formula used:
Real-life example:
A resistor has a resistance of 500 Ω. What is its conductance?
- Step 1: Resistance = 500 Ω
- Step 2: Conductance = 1 ÷ 500
- Step 3: Conductance = 0.002 S
- Step 4: Convert units
0.002 S = 2 mS
0.002 S = 2000 µS
Final Answer:
500 Ω corresponds to 0.002 Siemens.
Add another example:
A circuit has a resistance of 2 kΩ. Let's find the conductance.
- Resistance = 2 kΩ
- Convert: 2 kΩ = 2000 Ω
- Conductance = 1 ÷ 2000
- Conductance = 0.0005 S
- 0.5 mS
- 500 µS

The table below provides verified conductance values in S, mS, and µS for common electrical resistance values. Conductance decreases as resistance increases because conductance is the reciprocal of resistance.
| Resistance (Ω) | Conductance (S) | Conductance (mS) | Conductance (µS) |
|---|---|---|---|
| 1 Ω | 1 S | 1000 mS | 1000000 µS |
| 2 Ω | 0.5 S | 500 mS | 500000 µS |
| 5 Ω | 0.2 S | 200 mS | 200000 µS |
| 10 Ω | 0.1 S | 100 mS | 100000 µS |
| 50 Ω | 0.02 S | 20 mS | 20000 µS |
| 100 Ω | 0.01 S | 10 mS | 10000 µS |
| 500 Ω | 0.002 S | 2 mS | 2000 µS |
| 1000 Ω | 0.001 S | 1 mS | 1000 µS |
| 2000 Ω | 0.0005 S | 0.5 mS | 500 µS |
| 10000 Ω | 0.0001 S | 0.1 mS | 100 µS |
Note: Conductance decreases as resistance increases because conductance is the reciprocal of resistance.
Resistance to Conductance Frequently Asked Questions
To convert resistance to conductance, divide 1 by the resistance value. Conductance is the reciprocal of resistance, meaning you simply use the mathematical formula G = 1 / R to find the value in Siemens.
The formula for conductance is G = 1 / R, where G represents the conductance measured in Siemens (S), and R represents the electrical resistance measured in Ohms (Ω).
The SI unit of conductance is the Siemens, denoted by the symbol S. In older electrical engineering texts, it may also be referred to as the mho, which is ohm spelled backward.
Conductance decreases when resistance increases because they have an inversely proportional relationship. Since conductance is the exact reciprocal of resistance, a higher resistance to current flow naturally results in lower conductance.
Yes, kΩ and MΩ values can be converted into Siemens. First convert kilo-ohms or mega-ohms into base ohms, and then take the reciprocal. The result will typically be in smaller units like milliSiemens or microSiemens.
