kiloweber to femtoweber
Convert kiloweber (kWb) to femtoweber (fWb). Use an editable magnetic flux converter, conversion formula, and reference table.
1 kWb = 1e+18 fWb
Conversion formula
One kiloweber equals 1e+18 femtoweber. Multiply your value in kiloweber by this factor to get femtoweber. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 kiloweber:5 × 1e+18 = 5e+18 fWb

About these measurements
Magnetic flux describes the magnetic field through a surface.
The base reference used here is the weber. One kiloweber is 1,000 base units; one femtoweber is 1e-15 base units.
Important distinctions
Magnetic flux in webers differs from flux density in teslas.
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
