unit conversions

[pdrury]

I'm using a 2004 NAIP aerial photo with length units of meters as a background image. In order to calculate the sub-basin area correctly I need to select metric units.

Do I have to complete the project in metric units or can I convert the output results to english units?

Hi,

You should select metric units to calculate the areas properly as you correctly suggested. Then after automatically calculating the areas in "ha" or in "m^2", you change all the area values to english units means either in "ac" or in "ft^2" by calculating yourself. Then change the unit option to english units and re-enter all the converted values in the respective area fields and continue and finish your project in english units only.

Thanks,
