GBC ScreenShots Calculator
About:
GBC ScreenShots:
- Some of the worksheets are to some degree stand-alone, but most are also interlinked within this one spreadsheet so decisions made on earlier worksheets feed into later worksheets to carryout calculations.
- Later worksheets require more information or decisions by the user to make use of the earlier decisions, in more calculations.
- One sheets “UToWattsToCO2” require few inputs by the user, it assembles and calculates most things for you, you only need to choose the fuel source.
- The user is required to assess the results and decide if they wish to reconsider earlier decisions and go back to adjust values and to instantaneously improve the overall results.
