I have a question on unit conversion while using ArcCN runoff script. I am using metric measurements. My area data for landuse and soil maps are in squaremeters. Precipitation data is in mm. In original artical writers use inches for precipitation data but they have squaremeter unit for area data as I understood. Should I enter inches parameter for precipitation value or can I use mm parameter as I wanted to take runoff volume result in cubicmeters?
Any ideas there?
