Unit conversion

  1. Mar 6, 2006 #1
    i have to convert radiation flux density measured from the sun thats 1.64 langleys/min. Easy no?
    Well, I cant find what the SI unit for radiation flux density is, and its not on google.

    Anyone know just what the units is [NOT the conversion]

    By SI unit, do they mean the SI base units or just SI units. By definition, radiant flux density would be: Watts per unit area. Area in derived from length which in SI is the meter. Watts is derived from Joules per second, and Joules is derived from Newton meters, with Newtons coming from kilogram meter per second square.
