Conversion to lux (Light intensity)

  1. Aug 21, 2009 #1
    How would I go about converting 59.7 mw/m^2 to lux?

    I would appreciate any help I can't find an equality.

    lux

    Hi Petrucciowns! :smile:

    1 lux = 1 lumen per m2

    1 lumen = 1 candela steradian (http://en.wikipedia.org/wiki/Lumen_(unit))

    and (http://en.wikipedia.org/wiki/Candela#Definition) …

    Yes, but those conversions don't match up with the variables that I have.

    It depends on the wavelength.

    For 555 nm light, 1 W/m^2 is equivalent to 683 lux.

    For other wavelengths, multiply that by the human eye sensitivity function.
