The solar flux unit (sfu) is a convenient measure of spectral flux density often used in solar radio observations, such as the F10.7 solar activity index:
:1 sfu = 10
4 Jy = 10
−22 W⋅m
−2⋅Hz
−1 = 10
−19 erg⋅s
−1⋅cm
−2⋅Hz
−1.

The jansky (symbol Jy, plural ''janskys'') is a non- SI unit of spectral flux density, or spectral irradiance, used especially in radio astronomy. It is equivalent to 10−26 watts per square metre per hertz.
