BTU/hr to MCF - Are my conversions/calculations right?

I know it's the wrong forum, but it's the best fitting (I think).

I'm trying to figure the operating cost of my gas lights.

I know all of them together are using 4400 BTU/hr.
From my reading, one MCF of natural gas is equal to 1027 BTU.

So:

4400 / 1027 = 4.28 cuft per hr
4.28 * 24 = 102.72 * 30 = 3081.6 cuft per month

3081.6 / 1000 = 3.08 MCF per month.

My gas rate per MCF:
Delivery: 2.49
Capacity: .53
Commodity: 5.24
Total per MCF: \$8.26

So my gas lights are really costing \$25.44 a month? Or am I losing something in my math?

I had a gas yard light about 40 years ago. They aren't economic. Plus, they burn 24 hours per day - an electric light, with a photo cell or a manual switch, will burn maybe half that time.

Pull it out - just like they were a hundred years ago in houses.
