920 * 0.0048828125 = 4.49 V
1023 * 0.0048828125 = 4.99 V


As you see the sensor must be quite linear as they are relying on interpolation between 0.49 V and 4.49V

thank you for replying. It dawned on my that it was probably already scaled for 0-5v from the factory and was just displayed in a different way than Volts. I changed a few of the search words I was using and was able to find the formula you posted in an Arduino forum that described that it digitally converts 0-5v to 0-1023 Units.

thank you Ross
