JSutils gas use and prediction calculator EnCalcGU has been updated to optionally work in months and add a facility to clear the results log file. See history for more details. EnCalcGU calculates the cost of gas, allowing both the real cost based on meter readings and forward prediction based on the readings and elapsed time. The results can be saved to a log file for later analysis. The program can cope with different charging rates for gas based on a preset threshold, different calorific values/correction factors, imperial and metric meters, varying tax rates plus fixed charges and discounts enabling most charging models to be handled. It will also calculate the amount of CO2 generated.
