femtosiemens to kilosiemens
Convert femtosiemens (fS) to kilosiemens (kS). Use an editable electrical conductance converter, conversion formula, and reference table.
1 fS = 1e-18 kS
Conversion formula
One femtosiemens equals 1e-18 kilosiemens. Multiply your value in femtosiemens by this factor to get kilosiemens. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 femtosiemens:5 × 1e-18 = 5e-18 kS

About these measurements
Conductance is the reciprocal of resistance.
The base reference used here is the siemens. One femtosiemens is 1e-15 base units; one kilosiemens is 1,000 base units.
Important distinctions
To convert resistance into conductance, take a reciprocal. A direct unit conversion does not do that.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert fS to kS?
Multiply the quantity in fS by 1e-18. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the kilosiemens to femtosiemens converter.
