Conversion Formula

fWb = GWb × 1.000000000e+24

About Gigawebers

The gigaweber (GWb) equals 10⁹ Wb. An extreme unit used in solar and astrophysical magnetic flux accounting - active solar regions and coronal mass ejections (CMEs) are characterised by flux values in the GWb range. 1 GWb = 10⁹ Wb = 10¹⁷ Mx.

About Femtowebers

The femtoweber (fWb) equals 10⁻¹⁵ Wb. Used in SQUID magnetometer research to express flux noise spectral density; a typical high-T₂ SQUID has white flux noise of a few µΦ₀/√Hz, corresponding to sub-fWb/√Hz levels. 1 fWb = 10⁻¹⁵ Wb.
