I lost my note that provided the formula that compared the usage of propane vs electricity on dual-powered appliances (fridge, water heater, etc). If anyone has this info, I would really appreciate the info.
Eh!

Where can I get me some of that $1/gallon propane? If that were the case propane would be more cost effective.

Well, it's definitely an older article!
The OP was looking for "a formula" and might "only wish" he could find $1.00 a gallon propane!

It only makes a differance if you have to pay for electric. Where I stay in Forida (snowbird) propane is 3$ a gallon and electric is 16 cents a kilowatt. I have found that the best thing to do is run the fridge on electric and the water heater on gas and only turn it on when needed.

I wrote a program to do the calculation. It's free and you can download it HERE
The formulas used are in the help file if you want them for reference.

Quick and easy way. Multiply electric cost X 22. If propane cost is less than that result, then it is cheaper to use propane. Maybe not exact, but is close enough for government work.

That's pretty close.
The unadjusted factor is 26.8. Suburban Manufacturing says furnace efficiencies range from .7 to .8 and water heaters are about .7.
Multiplying the factor by .7 gives 18.8 and by.8 gives 21.4.
22 assumes the appliances are a little more efficient than they probably are, but as you say it's close enough for a quick approximation.
