I don't know the conversion formula or if there even is one, but the pressure at the quick connect is the same as out of the regulator That is 11" WC. That's standard and there is no difference from one model or year to the next. I've had the water heater, and fridge on propane and still had more that enough gas pressure to run a 30K BTU burner on a Camp Chef stove. You can operate any grill or stove that uses low pressure gas. If you have a grill with a regulator, you'll have o remove it.

I now have a Keystone Outback, but I try to help when I can.
