attoweber to femtoweber

Convert attoweber (aWb) to femtoweber (fWb). Use an editable magnetic flux converter, conversion formula, and reference table.

0.001

1 aWb = 0.001 fWb

Calculated in your browser

Conversion formula

fWb = aWb × 0.001

One attoweber equals 0.001 femtoweber. Multiply your value in attoweber by this factor to get femtoweber. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 attoweber:
5 × 0.001 = 0.005 fWb

About these measurements

Magnetic flux describes the magnetic field through a surface.

The base reference used here is the weber. One attoweber is 1e-18 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

How do I convert aWb to fWb?
