calculating energy costs per month
In principle it's simple enough but it depends on how you are billed and I
guess this is different country by country so for the UK if this helps:- m3 gas * 1.02264 * 39.6 / 3.6 will give killowatts used so multiply by cost per Killowat to get your bill. However there's another complication. 39.6 is the calorific value of the gas and this will vary month on month. Also you may find you are charged a higher rate for the first x killowatts and a lower rate for subsequent usage. Electricity is considerably simpler in that you are billed in Kw so a simple formula:- currenet meter reading-previous meter reading * cost per kw= bill ammount Hope this helps!!
