How to use Resistance and Conductance Converter
- Enter a nonnegative resistance or conductance.
- Choose the input and destination units.
- Convert and check whether the output is a scale change or a reciprocal.
Example: Resistance and Conductance Converter
Find conductance from resistance.
You add
Value: 1000. From: ohms. To: millisiemens.
You get
1000 Ω corresponds to 1 mS.
Options
- Resistance or conductance
- Ohms express resistance; siemens express conductance. Crossing between them takes a reciprocal and therefore refuses zero, while zero can remain valid within one quantity type.
- Decimal places
- Inspect the reciprocal result before choosing its display precision. Resistance and conductance can have very different magnitudes; 0, 2, 4, 6 or 8 places apply to the selected output quantity.
Supported inputs and limits
Positive finite values are required when taking a reciprocal. Zero can be scaled within one quantity but cannot produce a finite reciprocal. Impedance, phase and frequency-dependent components are outside this tool. Values accept at most 64 characters, 40 significant digits, 20 fractional places and magnitude 10¹⁸. Scientific notation has at most two exponent digits. Display rounding offers 0, 2, 4, 6 or 8 decimal places; small nonzero results stay visible.

The reciprocal is more than a prefix change
A resistance of 1000 Ω gives 1/1000 S, or 1 mS. Negative values retain their algebraic sign but do not establish that a passive component has that property. The converter does not measure a circuit.
Questions about Resistance and Conductance Converter
Why does a larger resistance give smaller conductance?
Conductance is the reciprocal of resistance in the stated resistive model. In base units, G = 1/R.
Can zero ohms become siemens?
It has no finite reciprocal. The tool refuses that request rather than presenting a finite number.
Is conductance the same as conductivity?
No. Conductance describes a component or path. Conductivity describes a material property and also involves geometry.
