# SDR Modeler parameter R and K

I am Koto.

I really appreciate for the advices by forum's staff.

I trying to use SDR modeler for analyzing supply for ecosystem services in watershed scale.

I have searched the R and K data in past research paper.

But I have found R and K data have different unit from InVEST model unit.

I found R data's unit is [tf・m^2/ha・h] and K data's unit is [h/m^2].

So I want to translate [tf・m^2/ha・h] to [MJ・mm/ha・h・yr] and [h/m^2] to [t･ha・h・(ha・MJ･mm)^-1].

Do you know how to translate the unit?
