Still working on it Yanche, and yes I'll be adding fields and better explanations. I'm still trying to determine what's the best way to go about working with the coal because if you have different BTU values for each field it will produce different results. I want to provide as many options as possible but want also avoid confusion and if there is two different sets of results that might cause a problem. Same problem with the gas because those fractions of a cent in the cost become cents when calculated.

Right now I'm working on finishing up the reverse calculator which will give you real numbers based on the first section, for example if you used $1K of coal(or whatever fuel) you could figure out what it would cost you for the other fuels.

You can now get reverse calculations based on a real world amount in the second section. From the drop down list select the fuel type and in the text box type in the cost. For example if you used $400 of fuel oil during a one month span you would select fuel oil and type in 400. The calculations for the other fuel types would reflect what it would cost if you were using them.


For those of you that have recently switched and have gone through a full year I'd be interested in knowing how accurate the estimates are. Understandably it's hard to get a truly accurate estimate but I'd at least like to know if it's in the ball park.

Note that it's important you fill out the first part as all calculations for the reverse calculations are based on those values.

It's about right for my #2 fuel oil vs. coal usage. How about math expressions in the reverse calculation. For example I have three 275 gallon fuel oil tanks. It would be nice to type in 3*275*3.00 for my total cost rather than having to first calculate it. 3.00 is the cost per gallon.

I could add that but right now I'm starting on something else and I'm going to put this aside for while.

I'll have it available next time I update code. I'm going to add other information under the reverse section like total BTU's, Units etc.
