Conversion Formula

MWb = fWb × 1.000000000e-21

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.

About Megawebers

The megaweber (MWb) equals 10⁶ Wb. Encountered in calculations for very large power plant generators and astrophysical applications; the total flux through a cross-section of a large sunspot group can reach MWb scale. 1 MWb = 10⁶ Wb = 10¹⁴ Mx.
