I’m confused as to why the results differ when I convert tons/year to tons/hectares/year, because when in tons/year, the most LULC contributor in sediment export is settlement; in tons/hectares/year its the bare soil with most sediment export contribution.

Hi @emerri -

Tons/year is a _sum total_ across all pixels of a particular LULC type. So if there are more pixels of a particular LULC type, this value will be larger, it increases with area.

Tons/hectare/year allows us to compare the values _per unit of area_. This way, the comparison is not skewed by the fact that some LULC types cover more area than others, or some watersheds are larger than others.
