Kero versus propane versus natural gas for heat

I thought this was fascinating. Now, lets see if we can figure out if propane is cheaper at 2.00 for a 16 ounce (one pound) bottle. Versus 3.00 or so a galon for kerosene.
I'm on "therm billing" and a quick call revealed that a therm is 100,000 BTU. So, looking at a typical bill, it cost me \$68 to get 13 therms delivered. Or about \$5.25 a therm.
In terms of propane in 16 ounce bottles, it would take about 5 bottles, or about \$10.00 produce a therm.
It would take about 3/4 galon of kerosene to produce a therm, which would be about \$2.00.
In refillable propane bottles (twenty pounders) I havn't priced them lately. But with the other fellow's figures, \$14 for 20 pounds is about .75 a pound. Needing 5# propane per therm, would be about \$3.75 per therm.
When the electric is out, and the furnace is dead, it's well worth ten bucks a therm. And kerosene is cheaper, but I have to drive to the store to get it.

"Is it cheaper to use kerosene or propane for heating , when kerosene is about \$2.50/gallon and propane about \$14/20 lbs?"
A quick Google gives about 135,000 btu/Gal for Kero and 21,600 btu/# or 91,000 btu/gal for Propane. I will leave the rest of the math to you.

You still need to figure in the cost of going to the store, unless you are going anyway, correct?
