I found this online. Kind of cool. Maybe someone here will find it useful. You can even download an exe and use it on your pc.

Beam Intensity System Dynamic Range Calculator
Exposure Value (EV)/Lux Converter
Foot-Candle/Lux Converter
Inverse Square Law Calculator
Lux/Foot-candles to Total Lumens Converter
QNDS Self-Calibration Calculator
Watts/m2 or Watts/cm2 to Total Watts Converter
Question:
The converter is based on an ISO of 100.
So let's say Lux 1000 = EV 8.5 at ISO 100.
What do I need to do to adjust it for ISO 320?
